Short Answer

Expert verified

Alkyl groups comprise a general formula .They are named by replacing “ane” of an alkane with “yl”.

Step by step solution

Alkyl groups

Alkyl groups comprise a general formula .They are named by replacing “ane” of an alkane with “yl”.

02

Drawing the eight 5-carbon alkyl groups

The prefix pent indicates that there are five carbon atoms in pentane. The arrangement of the carbon chains in straight chain and branched chain produces eight isomers. The structure of the isomers can be given as:

Eight carbon alkyl groups

There are seven constitutional isomers with the formula C4H10O. Drawas many as you can.

In each of the following sets, which structures represent the same compoundand which represent different compounds?

(a)

Increased substitution around a bond leads to increased strain. Take the four substituted butanes listed below, for example. For each compound, sight along the C2–C3 bond and draw Newman projections of the most stable and least stable conformations. Use the data in Table 3-5 to assign strain-energy values to each conformation. Which of the eight conformations is most strained? Which is least strained?

(a) 2-Methylbutane

(b) 2,2-Dimethylbutane

(c) 2,3-Dimethylbutane

(d) 2,2,3-Trimethylbutane
