Question

What are the hybridization and shapes of the following molecules?
$$\eqalign{ & \left( {\text{i}} \right)C{H_3}F \cr & \left( {{\text{ii}}} \right)HC \equiv N \cr} $$

A. $$\left( {\text{i}} \right)s{p^2},$$  trigonal planar; $$\left( {{\text{ii}}} \right)s{p^3},$$  tetrahedral
B. $$\left( {\text{i}} \right)s{p^3},$$  tetrahedral ; $$\left( {{\text{ii}}} \right)sp,$$  linear  
C. $$\left( {\text{i}} \right)sp,$$  linear ; $$\left( {{\text{ii}}} \right)s{p^2},$$  trigonal planar
D. $$\left( {\text{i}} \right)s{p^2},$$  trigonal planar, $$\left( {{\text{ii}}} \right)s{p^2},$$  trigonal planar
Answer :   $$\left( {\text{i}} \right)s{p^3},$$  tetrahedral ; $$\left( {{\text{ii}}} \right)sp,$$  linear
Solution :
$$\left( {\text{i}} \right)C{H_3}F{\text{ - }}s{p^3}$$    hybridised carbon, tetrahedral shape $$\left( {{\text{ii}}} \right)HC \equiv N{\text{ - }}sp$$    hybridised carbon, linear shape.
