Question

Which of the following is 3-Hexyne HC identicalto C-CH_2-CH_2-CH_3 CH_3-C identicalto C-CH_2-CH_2-CH_3 CH_3-C identicalto C-CH_2-CH_3 CH_3-CH_2-C identicalto C-CH_2-CH_2 Which of the following is correctly named? CI-CH_2-C identicalto C-CH_2-CH_3 1-Chloro-3-pentyne Cl-CH_2-C identicalto C-CH_2-CH_2-Br 5-Bromo-1-chloro-2-pentyne CI-CH_2-C identicalto C-CH_2-CH_2-CH_3 1-Chloro-3-hexyne Br-CH_2-C identicalto C-CH_2-CH_2-CI 5-Bromo-1-chloro-3-pentyne Identify the correct statement of Bromination of 2-Butyne with Br_2 The product is trans-2, 3-dibromobutane The product is cis-2, 3-dibromobutane The product is trans-2, 3-dibromobutyne The product is cis and trans-2, 3-dibromobutane None of them Hydrogenation of 2-Butyne gave cis and trans mixture of -2-butene. What would be the the catalyst? Pd/C Pd/CaCO_3 Li/NH_3 BH_3/THF All Identify the product of the reaction of 1-Butyne with BH_3/THF and H_2 O_2/H_2 O, at pH 8.

Explanation / Answer

1.

3-Hexyne, in this name, hex indicates that the parent contineous carbon chain contains 6 carbon atoms.

yne indicates that there is triple bond.

The numerical 3 indicates that the position of triple bond at third carbon.

So, the compound given D is the 3-hexyne.

Answer: D.
