I know the correct answer is either a or d. Can anyone explain which one it is and why? CH3C ≡ CCH2CH2Cl is named: a. 1-chloro-3
lara31 [8.8K]

Answer:

D.

Explanation:

CH₃C≡ CCH₂CH₂Cl

Since there are 5 carbons so the suffix used is "pent"

There is a triple bond so its alkyne

So the compound becomes 2-pentyne (2 because the triple bond is with the 2nd carbon)

Then,

The functional group of chlorine is attached with 5th carbon So the compound becomes

5-chloro,2-pentyne
