Question

Choose the correct option that best indicate the hybridized orbital type bond length and bond angle for methane
A. Sp3 154 pm and 190
B. Sp 134 and 180
C. Sp2 134 pm and 120
D. Sp3 134 pm and 120

Answer 1

Answer:

Option D

Explanation:

These are based on calculation which one should remember.

The data are as following

hybridised orbital    Angle    Distance(pm)

sp3                            109          154

sp2                            120          134

sp                               180          120

As the s character increase the bond becomes shorter we can see that from the data.

sp3 forms tetrahedral shape. The angle for tetrahedral is 109° 25'

sp2 forms planar trigonal shape having 120°

and sp forms planar shape having 180°

In the picture the green orbitals are vacant orbital and red one are hybridised
