In 3,3-dimethylhex-1-en-4-yne, there are ____ sp3, ____ sp2 and ____ sp hybridised carbon atoms respectively. (1) 2, 4, 2 (2) 2, 2, 4 (3) 3, 3, 2 (4) 4, 2, 2

1. 2, 4, 2
2. 2, 2, 4
3. 3, 3, 2
4. 4, 2, 2

Correct answer: 4, 2, 2

Solution

In 3,3-dimethylhex-1-en-4-yne, the carbon atoms are hybridized based on their bonding: four carbons are single-bonded (sp3), two are involved in a double bond (sp2), and two are in a triple bond (sp), leading to the correct count of 4 sp3, 2 sp2, and 2 sp hybridized carbons.
