Chapter 5: Problem 27

Give the proper name for the compound \(\mathrm{TiC}\).

Short Answer

Expert verified
The proper name for the compound \(\mathrm{TiC}\) is Titanium Carbide.

Step by step solution

01

Identify the elements involved

The formula \(\mathrm{TiC}\) consists of two elements: Titanium (\(\mathrm{Ti}\)) and Carbon (\(\mathrm{C}\)).
02

Apply the naming rules for binary compounds

Binary compounds are named by using the name of the more electropositive element (usually a metal) followed by the name of the more electronegative element (usually a non-metal), with the ending of the electronegative element changed to "-ide". In this case, Titanium is the more electropositive element and Carbon is the more electronegative element.
03

Name the compound

Given the above naming rule, we write the name of the electropositive element first, which is Titanium, followed by the name of the electronegative element, Carbon, with its ending changed to "-ide". Thus, the proper name for the compound \(\mathrm{TiC}\) is Titanium Carbide.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Binary Compounds
Understanding binary compounds is fundamental to grasping the basics of chemical nomenclature. A binary compound consists of exactly two different elements, which can be either both nonmetals, a metal and a nonmetal, or a metalloid and a nonmetal. The simplicity of these compounds allows for a straightforward application of nomenclature rules to determine their systematic names. For example, if we consider the compound composed of titanium and carbon, \(\mathrm{TiC}\), it falls under the category of a binary compound that consists of a transition metal and a nonmetal.
Chemical Nomenclature
Chemical nomenclature is the system of naming chemical substances to ensure uniformity and clarity when referring to them. This system is vital for students and professionals in chemistry, pharmaceutical, and other related fields, as it enables precise communication without confusion. Each compound's name holds information about its composition and structure, allowing chemists to predict its properties and behaviors. It's akin to having a universal language for scientists globally.
Electropositivity
Electropositivity refers to an element's ability to donate electrons during a chemical reaction, which in turn determines its position in naming binary compounds. Generally, metals are more electropositive compared to nonmetals. The more electropositive element in a binary compound is usually listed first in the compound name. This indicates the element that tends to lose electrons and form positive ions (cations) in compounds. For instance, in titanium carbide, \(\mathrm{TiC}\), titanium is a transition metal and has a higher electropositivity than carbon. This means titanium will be the element that is named first.
Compound Naming Rules
Correctly naming compounds is crucial for communication in science. For binary compounds, the naming rules are as follows:

  • Start with the name of the more electropositive element (usually the metal).
  • Add the name of the more electronegative element (usually the nonmetal), modifying the suffix to '\(-ide\)'.
Following this rule, the binary compound \(\mathrm{TiC}\) is named 'titanium carbide'. Titanium, being the more electropositive element, is mentioned first, followed by carbide, which comes from the root name of carbon with the '-ide' ending. Understanding and applying these simple rules will significantly aid in deciphering and naming chemical compounds.

A student claims that the bonds in ozone are really not double bonds or single bonds but somewhere between (roughly \(1.5\) bonds between each oxvgen). Justify this statement.

Give the name of the following binary compounds of transition metals using both the modern and older systems: (a) \(\mathrm{CuCl}\) and \(\mathrm{CuCl}_{2}\) (b) \(\mathrm{Fe}(\mathrm{OH})_{2}\) and \(\mathrm{Fe}(\mathrm{OH})_{3}\)

Ethers are compounds of \(\mathrm{C}, \mathrm{H}\), and \(\mathrm{O}\) that are often used as solvents. One particular ether molecule has the formula \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} .\) The structure is such that both carbons are attached to the oxygen atom, and there are no \(\mathrm{O}-\mathrm{H}\) bonds. Starting with dot diagrams for the atoms, draw a dot diagram for this ether molecule. How many bonding pairs does the molecule have? How many lone pairs?

Draw dot diagrams for \(\mathrm{Cl}_{2}\) and for \(\mathrm{MgCl}_{2}\) (put \(\mathrm{Mg}\) in the middle) that agree with the type of bonding occurring in each. (That is, show electrons as being shared or transferred, and if they are transferred, show the charges of the resulting ions.)
