3. For the reaction: 2X + 3Y 3Z, the combination of 2.00 moles of X with 2.00
lions [2927]

Answer:

Explanation:

Considering the reaction: 2X + 3Y = 3Z, combining 2.00 moles of X with 2.00 moles of Y results in the production of 1.75 moles of Z.

      2 mol       2 mol   1.75 mol

       2X     +    3Y       =    3Z

2 mol is required with 3 mol to yield 3 mol.

3 mol Z / 3 mol Y =  1 to 1

should yield 2 mol Z

1.75 / 2 = 87.5 % production yield

Reaction of (r)-2-chloro-4-methylhexane with excess nai in acetone gives racemic 2-iodo-4-methylhexane. what is the explanation
alisha [2963]

I believe this question has five choices available:

 

>an SN2 process has happened with reversal of configuration

>racemization followed by an S N 2 reaction

>an SN1 process has occurred resulting in reversal of configuration

>an SN1 reaction has taken place due to the formation of a carbocation

>an SN1 event followed by an S N 2 “backside” attack

 

 

 

The correct choice is:

an SN1 reaction has occurred due to carbocation formation
