Carbon percentage is maximum in
Options
(a) ethylene glycol
(b) gammexane
(c) pyrene
(d) PVC
Correct Answer:
PVC
Explanation:
PVC is a polymer with large number of C-atoms.
Percentage of C = (Mass of C / Mass of substance ) × 100
CCl₄ = (12 / 154) × 100 = 7.79%
C₆H₆Cl₆ = (72/291) × 100 = 24.74%
CH₂OH – CH₂OH = (24 / 62 ) × 100 = 38.70%.
