MOST COMMON ORGANIC QUESTIONS:

Test for double bond / alkene

Bromine water

Turn from brown to colourless in case of carbon double bonds (alkenes)

Type of reaction: electrophilic addition

Define stereoisomerism

Molecules with same structural formula

Same molecular formula

Different arrangements of atoms in space

Explain why X is the major product of the reaction while only small amounts of Y is produced

N carbocation has the least number of H atoms bonded to it, it is more stable

Due to positive inductive effect

There are more electron donating methyl groups

Reducing charge density on C+

Tollens Reagent is which reaction

oxidation / reduction

2,4 DNPH is which reaction

condensation

Ketone with NaBH4 is which reaction

reduction / addition

Aldehyde and HCN is which reaction

addition

ALKENE + steam is which reaction

addition

Alkene reactions are which reactions

Alkene reactions are either electrophilic addition or redox, kmno4 reagent used are redox and the rest of the alkene are electrophilic addition.

Halogenoalkane reactions are which reactions

Halogenoalkane reactions are all nucleophilic substitution except to alkene which is elimination reaction

Structural isomers

Same molecular formula but different structural formula/bond arrangement (types- chain, positional, functional group isomerism)

How does an sp2 and sp3 hybridization occurs and their bond angles in carbon atoms

Sp2: overlap of 2 s with 2 p atomic orbitals: 116-124

Sp3: overlap of 2 s with all three 2 p atomic orbitals: 106-112
