Match column A with column B.
| Column - A | Column - B |
| a. Alkanes | i. Ethane |
| b. Alkanes | ii. Butyne |
| c. Alkanes | iii. Propene |
| d.Aldehyde | iv. Methanal |
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. a–i, b–ii, c–iii, d–iv..
-
a. Alkanes → i. Ethane: Alkanes are saturated hydrocarbons containing only single bonds. Ethane (C₂H₆) is a simple alkane.
-
b. Alkynes → ii. Butyne: Alkynes are unsaturated hydrocarbons with at least one triple bond. Butyne (C₄H₆) belongs to this group.
-
c. Alkenes → iii. Propene: Alkenes are unsaturated hydrocarbons with a double bond. Propene (C₃H₆) is a typical alkene.
-
d. Aldehyde → iv. Methanal: Aldehydes contain a –CHO group. Methanal (formaldehyde, HCHO) is the simplest aldehyde.
Final Match:
a–i, b–ii, c–iii, d–iv.
This classification is based on the type of bonds and functional groups present in the compounds, which distinguishes alkanes, alkenes, alkynes, and aldehydes.
