NEET Organic Chemistry

Question 1

What is the general formula for alkanes (saturated hydrocarbons)?

Accepted Answer

CnH2n+2

Answer

Alkanes follow the general formula CnH2n+2, as each carbon forms four single bonds with hydrogen or other carbons.

Question 2

Which functional group is present in alcohols?

Accepted Answer

-OH

Answer

Alcohols are characterized by the hydroxyl (-OH) functional group attached to a carbon atom.

Question 3

What type of reaction converts alkenes to alkanes by adding hydrogen?

Accepted Answer

Hydrogenation

Answer

Hydrogenation adds H2 across a double bond in an alkene to form a saturated alkane, typically using a metal catalyst like Ni or Pt.

Question 4

Which compound is the simplest aromatic hydrocarbon?

Accepted Answer

Benzene

Answer

Benzene (C6H6) is the simplest aromatic hydrocarbon, featuring a ring of six carbon atoms with delocalized pi electrons.

Question 5

What is the IUPAC name for CH3-CH2-OH?

Accepted Answer
