The number of grams of bromine that will completely react with 5 g of pentene is:
[Atomic mass of \(\mathrm{Br}=80 \mathrm{u}\) ]
- A 8.4 g
- B 11.4 g
- C 22.4 g
- D 54.2 g
Answer & Solution
Correct Answer
(B) 11.4 g
Step-by-step Solution
Detailed explanation
The chemical formula for pentene is \(C_{5}H_{10}\). The reaction of pentene with bromine is an addition reaction: \(C_{5}H_{10} + Br_{2} \rightarrow C_{5}H_{10}Br_{2}\) The molar mass of pentene (\(C_{5}H_{10}\)) is \(5 \times 12 + 10 \times 1 = 70\) g/mol. The molar mass of…
