Answer

c) CH₁

Step-by-step explanation

Given that:

A compound has a molecular weight of 114.22 g/mol

The empirical formula for the compound is C₄H₉

What to find:

To determine the molecular formula for the compound.

Step-by-step solution:

(Empirica formula)n = (Molecular weight)

(C₄H₉)n = 114.22

(4 x 12.01 + 9 x 1.01)n = 114.22

(48.04 + 9.09)n = 114.22

57.13n = 114.22

Divide both sides by 57.13

n = 114.22/57.13

n = 2

Therefore, the molecular formula for the compound is (C₄H₉)₂ = CH₁

The correct answer is option c) CH₁
