Compound A formed in the following reaction reacts with B gives the product C. Find out A and B. CH 3 – C ≡ CH + Na – → Α ⎯→ ⎯ B CH 3 – C ≡ C – CH 2 – CH 2 + NaBr (C) CH 3

1. A = CH 3 – C ≡ , a N C + − B = CH 3 – CH 2 – CH 2 – Br
2. A = CH 3 – C ≡ , a N C + − B = CH 3 – CH 2 – CH 3
3. A = CH 3 – CH 2 – CH 3 , B = CH 3 – C ≡ CH
4. A = CH 3 – CH = CH 2 , B = CH 3 – CH 2 –CH 2 – Br

Correct answer: A = CH 3 – C ≡ , a N C + − B = CH 3 – CH 2 – CH 2 – Br
