MCQ
How many moles of $BH_3$ are needed to react completely with $2\, mole$ of $1$-pentene in hydroboration-oxidation reaction ?
- A$2$
- B$3$
- ✓$0.67$
- D$1.5$
✓
Answer
Correct option: C.
$0.67$
c
$(c) \,3 \,mole$ of alkene reacts with $1\, mole$ of $BH_3$
$\therefore \,2 \,mole$ of alkene $\to 2/3 \,mole$ of $BH_3$
$(c) \,3 \,mole$ of alkene reacts with $1\, mole$ of $BH_3$
$\therefore \,2 \,mole$ of alkene $\to 2/3 \,mole$ of $BH_3$
