Question

Circle True or False: Free radical bromination of methane is a good way of making chloromethane: lsopropanol is a secondary alcohol Hydroxide ion can be a good base or a good nucleophile There are two enantiomers of cis 1, 2- cyclopentanediol (+/-) -2 cholorobutane is racemic 3-Chlorocyclohexanol has two chiral centers Cyclohexane (chair) has six axial hydrogens Free radical halogenation can generate new asymmetric centers Ethers can be prepared from alcohols suing SN-2 chemistry Ethane can be free radical chlorinated up to six times Ethylene is a good source of ethanol Dehydration of 4- chlorobutane gives 1- butene.

Explanation / Answer

1) false bromination can not give chloroderivative.

2) Yes iso propanol is CH3CH(OH)CH3 a secondary alcohol

3)yes OH- is a good base and good nucleophile

4) No the molecule has plane of symmetry

5) Yes . 2-chloro butane has one chiral carbon

6) Yes it has two chiral centers , but exists as meso due to plane of symmetry

7) Yes . chyclohexane has each C with one axial H

8) Yes, if the C were a sterogenic center..

9) Yes. First -Oh is converted to -OTs and then william synthesis (SN2) with alkoxide

10) Yes C2H6 with six chlroinations change to C2Cl6

11) ethylene is easily converted to ethanol.

12) No dehydration means removal of water . Chlorobutane has no OH .
