# Question: part 1. Write the Lewis structure of dimethylamine, (CH3)2NH. part 2). Choose the correct variant of its geometry. –Free Chegg Question Answer

part 1. **Write the Lewis structure of dimethylamine, (CH3)2NH.**

part 2). **Choose the correct variant of its geometry.**

a)Each inner has atom SN = 5, so the electron group geometry about each inner atom is octahedral.

b) Each inner atom has SN = 4, so the electron group geometry about each inner atom is tetrahedral. The shape about the N atom is tetrahedral also.

c) Each inner has atom SN = 4, so the electron group geometry about each inner atom is tetrahedral. The shape about the N atom is trigonal pyramidal, like ammonia.

d) Each inner atom has SN = 3, so the electron group geometry about each inner atom is trigonal pyramidal. The shape about the N atom is tetrahedral, like ammonia.

**part 3. Choose the correct variant of its a ball-and-stick model if dimethylamine, (CH _{3})_{2}NH, can be showing as an ammonia molecule with two hydrogen atoms replaced by CH_{3} groups.**
