Question

in which of these substances is significant hydrogen bonding possible: methylene chloride (CH2Cl2), phosphine (PH3), chloramine (NH2Cl), acetone (CH3COCH3) ?

Answer 1

Answer:

Significant hydrogen bonding is possible in $NH_{2}Cl$

Explanation:

• Hydrogen bonding takes place between an electronegative atom (O, N and F) and a H atom attached to those electronegative atoms.
• Lewis structure reveals that H atom attached to N in $NH_{2}Cl$.
• In all other compounds no such H atom is present attached to O or N or F.
• Hence significant hydrogen bonding is possible only in $NH_{2}Cl$
• Lewis structures are given below.
