3. Use the following two-step mechanism to answer the questions below. HNO2+ HCl →Cl–+ NO++ H2O
CH3NH2+ NO++ Cl–→CH2N2+ H2O + HCl
a) What is the balanced chemical equation for the overall reaction?
b)The catalyst in this reaction is:
c)The intermediate in this reaction is:

28528289 29823282 8298232 39858

a

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
