1a. In organic chemistry, reduction can be defined as:
Select one:
a. the addition of an oxygen bond
b. the addition of a halogen bond
c. none of these are correct
d. the addition of a hydrogen bond
1b. Reducing a double bond to create a secondary alcohol will require what type of starting substrate?
Select one:
a. aldehyde
b. alkyne
c. ketone
d. alkene
1c. Which of the following reaction is NOT an oxidation reaction?
Select one:
a. H2C=O→HCOOH
b. CH3OH→H2C=O
c. CH4→CH3OH
d. CO2 → HCOOH
1d. Which of the following reagent, does NOT have a nucleophilic carbon?
Select one:
a. CH3CH2ONa
b. CH3Li
c. CH3CH2MgCl
d. . CH3MgBr
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.
