Draw the complete structures of bromomethane, bromoethane, 2 -bromopropane and tertbutyl bromide. Arrange them in order of increasing steric hindrance.

Draw the complete structures of bromomethane, bromoethane, 2 -bromopro

1.	Draw the complete structures of bromomethane, bromoethane, 2 -bromopropane and tertbutyl bromide. Arrange them in order of increasing steric hindrance.
Answer» Solution :(i) Bromomethane, `CH_3 Br: H- UNDERSET(underset(H)\|)overset(overset(H)\|)C - Br` (ii) Bromoethane, `CH_3 CH_2 Br:H - underset(underset(H)\|)overset(overset(H)\|)C - underset(underset(H)\|)overset(overset(H)\|)C - Br` (iii) 2- Bromopropane, `CH_3 CH Br CH_3 : H - underset(underset(H)\|)overset(overset(H)\|)C- underset(underset(Br)\|)overset(overset(H)\|)C - underset(underset(H)\|)overset(overset(H)\|)C- H` (IV) tert-Butyl bromide, `(CH_3)_3 Br: H- underset(underset(H)\|)overset(overset(H)\|)C - underset(underset(H-underset(underset(H)\|)C-H)\|)overset(overset(H-overset(overset(H)\|)C-H)\|)C - Br` Increasing order of STERIC hindrance : Bromomethane < Bromoethane < 2-Bromopropane < tert-Butyl bromide.
