Question

A mixture of 1-heptyne, 2-heptyne, and 3-heptyne was hydrogenated in the presence of a platinum catalyst until hydrogen uptake ceased. If one assumes that the hydrogenation went to completion, how many distinct seven-carbon hydrocarbons were produced? 8 1 6 2 3 Which of the following statements about ethane, C_2H_4, is incorrect? The H-C-H bond angles are approximately 120 degree. All of the hydrogen atoms are in the same plane. The carbon atoms are sp^2 hybridize. The H-C-H bond angles are approximately 109.5 degree. There is a total of five sigma a bonds.

Explanation / Answer

Q15

if we are totally hydrogenating them, they all form heptane, therefore the answer is B =1

C7H16

Q16

H2C=CH2

a) is true, sp2 hbridiation

b) true, same planar

c) true, due to hybridization

d) false, those are not tetrahedrical

e) true

choose D
