From: JEE Main 2022 (Online) 25th June Morning Shift
Question
Number of grams of bromine that will completely react with 5.0 g of pent-1-ene is ___________ 102 g. (Atomic mass of Br = 80 g/mol) [Nearest Integer]
Enter your answer
Show full solutionCorrect answer: 1142.8
Step-by-step explanation
Molar mass of C5H10 = 12 5 + 10 = 70 gm
Given mass of C5H10 = 5 gm
Moles of C5H10 =
From reaction,
1 mole of C5H10 reacts with 1 mole of Br2
moles of C5H10 reacts with moles of Br2
Reacted Br2 = 160 gm
= 11.428 gm
= 1142.8 102 gm
1143 102 gm
