Question

question 13 (1 point)
use the following information to answer the next question.
chloroform (chcl₃) is generally used as an anesthesia in medical
treatment. it is also used in the chemical industry to produces dyes and
pesticides. it is generally obtained by the action of chlorine on a
hydrocarbon in the presence of sun rays.
cl₂ + x → chloroform
if x is the hydrocarbon used for the production for chloroform, compound x is
a) propyne
b) ethane
c) propane
d) ethene
e) methane

Explanation:

Step1: Analyze the formula of chloroform

Chloroform is \(CHCl_3\). It has one carbon atom.

Step2: Check the number of carbon atoms in each option

• Prop - yne (\(C_3H_4\)) has 3 carbon atoms.
• Ethane (\(C_2H_6\)) has 2 carbon atoms.
• Propane (\(C_3H_8\)) has 3 carbon atoms.
• Ethene (\(C_2H_4\)) has 2 carbon atoms.
• Methane (\(CH_4\)) has 1 carbon atom.

Since chloroform (\(CHCl_3\)) has one carbon atom, the hydrocarbon \(X\) should also have one carbon atom.

Answer:

E. methane
