Orgo! Located in photo. 5.The product in the following reaction is formed as a result of a 1,2-methyl shift fromthe initially formed 2° carbocation. Which intermediate correctly illustrates thatcarbocation rearrangement?H,SO,H,OOHOH2(а)(b)(c)(d)6. When HBr is added to 1-butene (as shown in the following reaction equation) thenewly formed stereocenter must be a racemic mixture of both R & S formsbecause (a) 1-butene forms a 1° carbocation, (b) the intermediate 2° carbocationcan be attacked from either face, (c) the intermediate 2° carbocation rearrangesby 1,2 -hydride shifts before the Br- attacks, (d) the two products are achiral:BrtCH CHCH,(S)-2-bromobutaneHBrCH,Planar carbocationCH CHCH,CH:BetCH:Be:(R)-2-bromobutane7. In the reaction shown below which converts an alkene to an alcohol, what speciesacts as the nucleophile in the reaction with the carbocation intermediate?(a) a sulfuric acid molecule, (b) a hydronium ion (c) a neutral water molecule,(d) the C=C of the alkene.slowR-CH=CH2 + H-OSO3HR-CHCH3H20R-CHCH3R-CHCH3 + H3O:SHCHSHO:H-
