A
(A) 1 and 2 only
B
(B) 1 and 4 only
C
(C) 1, 2 and 4 only
D
(D) All are correct
Answer
(D) All are correct
Explanation
Solution
Explanation:
All the given options are correctly matched.Aldehyde has CnH2O general formula. Example: Ethanal −C2H4O,n=2Carboxylic acid has CnH2nO2 general formula. Example: Propionic acid −C3H6O2,n=3Cycloalkane has CnH2n general formula. Example: Cyclobutane −C4H8,n=4Alkane also has CnH2n+2 general formula. Example: Ethane −C2H6,n=2Hence, the correct option is (D).
