Homework Answers

Answer #1

1a. Addition of a hydrogen atom or gain of electrons to decrease the oxidation state is considered as reduction reaction. Hence, option D is correct.

1b. Ketones are reduced to secondary alcohols in a reduction reaction. Hence, option C is correct.

1c. Carbon aton in CO2 has an oxidation state of +4, while in HCOOH it has OS of +2. So, that'd make this conversion a reduction reaction. Hence, option D is correct.

1d. All the molecules listed here are nucleophiles.
