MCQ
Which of the following is not correct regarding basic strength?
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
c
Amines are basic in nature. There basic nature is result of presence of lone pair of electrons on nitrogen. Amines when dissolved in water attract a proton to form alkylammonium ion and a hydroxide ion. The order of basicity is primary $ < $ tertiary $ > $ secondary. The aromatic amines are weaker bases than ammonia.
