Chapter 1: Q27P (page 28)

What orbitals are used to form 10 sigma bonds in propane( CH 3CH 2CH3)?

Short Answer

Expert verified

In propane 2, sigma bonds are formed by SP3 -SP3overlap and rest eight sigma bonds are formed by the overlap of SP3with s-orbital.

Step by step solution

01

Identifying the type of sigma bonds in propane

InthereCH3CH2CH3 are 10 sigma bonds which consist of 2 C-Cbonds and rest 8 C-Hbonds.

02

Identifying the orbitals used 

All the bonds in propaneCH 3CH 2CH3are single bonds. To bond with four atoms, each carbon in propane will use 4SP3 orbitals. Among 4 SP3 orbitals, one is used to bond with the SP3 orbital of the next carbon, thus, forming C-Cbond.

The other 3SP3 orbitals are used to bond with s-orbitals of the hydrogen attached to the carbon, thus, forming C-Hbond.

03

Final conclusion

The 2C-C bonds are formed bySP3--SP3 overlap and the rest 8 C-Hsigma bonds are formed by SP3-Soverlap.

Calculate the percentages of α-d-glucose and β-d-glucose present at equilibrium from the specific rotations of α-d-glucose, β-d-glucose, and the equilibrium mixture. Compare your values with those given in Section 20.10. (Hint:The specific rotation of the mixture equals the specific rotation of α-d-glucose times the fraction of glucose present in the α-form plus the specific rotation of β-d-glucose times the fraction of glucose present in the β-form.)
