The structure of four Chloroalkanes W X, Y and Z are shown:
(CH₃)₂CHCH(Cl)CH₃ W
CH2(Cl)CH3 X
(CH₃)3CHCH₂Cl Y
(CH₃)₂CHC(CH₃)₂Cl Z
Select the Chloroalkane classified as tertiary
- A
W only
- B
X only
- C
Y only
- D
Z only
The correct answer is Z only. In Z, the carbon atom that carries the chlorine is attached to three other carbon atoms, making it a tertiary carbon. In contrast, W and Y are secondary chloroalkanes, as their chlorine-bearing carbon atoms are attached to two other carbon atoms. X is a primary chloroalkane, where the chlorine atom is attached to a carbon connected to only one other carbon atom. Understanding the classification of carbon atoms based on their bonding is crucial for solving this question.
W is a secondary chloroalkane, as the chlorine atom is attached to a carbon that is connected to two other carbon atoms.
X is a primary chloroalkane, as the chlorine atom is attached to a carbon that is connected to only one other carbon atom.
Y is a secondary chloroalkane, as the chlorine atom is attached to a carbon that is connected to two other carbon atoms.
Z is a tertiary chloroalkane, as the chlorine atom is attached to a carbon that is connected to three other carbon atoms.
