Question

A mixture of consisting of 1-pentyne, 2-pentyne, 3-pentyne reacted with excess of H_2 in the presence of Pd/C to completion. How many different products were obtained? a. No reaction b. 1 c. 2 d. 3 What is the approximate C-C-C bond angle in propyne? a. 90 degree b. 109 degree c. 120 degree d. 180 degree Which of the following is more acidic? a. butane b. 1-butene c. 1-butyne d. 2-butyne What is the major organic product obtained from the following reaction? a. 7-methyl-5-nonyne b. 5-bromo-3-methyl-4-nonyne c. 2-ethyl-3-octyne d. 3-methyl-4-nonyne What is the major organic product obtained from the following reaction? a. (E) - 3, 4-dibromohexane b. 3, 3-dibromohexane c. (Z) - 3, 4-dibromohexene d. 3, 3, 4, 4-tetrabromohexane

Explanation / Answer

13) Among the given alkynes, there are no existance of 3-pentyne. Hence reduction of given alkynes 1-pentyne gives one product. 2-pentyne gives one product. Hence, two total products will be formed. Hence the answer is C)

14) As it is linear geometry, the bond angle is 180o. Hence answer is d)

15) Alkynes are more acidic as those are having more "s" cheracter. among the two alkynes given, 1-butyne is having greater acidity because of having terminal H. Hence option is c)

16) Option a) is correct.

17) b) is correct.
