What is the definition of an organic compound?

An organic compound is any compound that contains carbon atoms bonded together with covalent bonds.

What is resonance in organic chemistry?

Resonance in organic chemistry refers to a situation where a molecule has two or more possible structures due to the delocalization of electrons.

What is the difference between alkanes and alkenes?

Alkanes only contain single bonds between all carbon atoms while alkenes contain at least one double bond between two carbon atoms.

What is the general formula for alkanes and alkenes?

The general formula for alkanes is CnH2n+2 while the general formula for alkenes is CnH2n.

What is the functional group in alcohols?

The functional group in alcohols is the hydroxyl group (-OH).

What is the difference between primary, secondary, and tertiary carbon atoms?

Primary carbon atoms are bonded to one other carbon atom, secondary carbon atoms are bonded to two other carbon atoms, and tertiary carbon atoms are bonded to three other carbon atoms.

What is the definition of chirality in organic chemistry?

Chirality in organic chemistry refers to the property of a molecule that is not superimposable on its mirror image.

What is the purpose of a Grignard reagent in organic chemistry reactions?

Grignard reagents are used as nucleophiles in organic chemistry reactions to add a carbon atom to a carbonyl compound.

What is the difference between an electrophile and a nucleophile?

An electrophile is an electron-deficient species that seeks out electrons while a nucleophile is an electron-rich species that seeks out electron-deficient species.

What is the purpose of a catalyst in organic chemistry reactions?

A catalyst is a substance that speeds up a chemical reaction without being consumed in the reaction.

What is the difference between an SN1 and SN2 reaction?

SN1 reactions involve a two-step mechanism and the formation of a carbocation intermediate while SN2 reactions involve a one-step mechanism and the simultaneous breaking and formation of bonds.

What is the difference between an E1 and E2 reaction?

E1 reactions involve a two-step mechanism and the formation of a carbocation intermediate while E2 reactions involve a one-step mechanism and the simultaneous breaking and formation of bonds.

What is the difference between an aldehyde and a ketone?

An aldehyde has a carbonyl group at the end of a carbon chain while a ketone has a carbonyl group in the middle of a carbon chain.

What is the difference between a primary, secondary, and tertiary alcohol?

A primary alcohol has one carbon atom bonded to the hydroxyl group, a secondary alcohol has two carbon atoms bonded to the hydroxyl group, and a tertiary alcohol has three carbon atoms bonded to the hydroxyl group.

What is the difference between an oxidation and a reduction reaction?

An oxidation reaction involves the loss of electrons while a reduction reaction involves the gain of electrons.
