Q. Consider the following reactions

$A \to (i) C H_{3} M g B r B \to C u 2 - m e t h y l - 2 - b u t e n e$

The mass percentage of carbon in A is

33.33

6.67

16.66

66.67

$% c a r b o n = \frac{A t o mi c ma ss \times A t o mi c i t y}{M o l a r ma ss} \times 100$

$= \frac{12 \times 4}{72} \times 100 = 66.66%$
