Question

What is ue 16. a) Beta-carotene, CaoHss, is found in carrots and many other veggies. degree of unsaturation of beta-carotene? Show your work 17. Consider this energy diagram A) Label an intermediate state "IS" B) Label a transition state "TS". Time Which type of reaction does this diagram most nearly describe? a) an overall favorable reaction (exothermic) with a C) b) an overall favorable reaction (exothermic) with a c) an overall unfavorable reaction (endothermic) with a d) an overall unfavorable reaction (endothermic) with a fast first step and a slow second step slow first step and a fast second step fast first step and a slow second step slow first step and fast second step 18. Consider this reaction: H3 H This reaction is a(n) CH3-C-CH2 +H20 H+ catalyst, heat a) addition b) alimination c) rearrangement reaction d) substitution

Explanation / Answer

Degree of unsaturation of betacarotene can be calculated as follow-

Degree of unsaturation = ( number of carbon atoms - no. Of hydrogen atom/2 ) + 1

Deree of unsaturation = ( 40 - 56/2 ) + 1

= ( 40 - 28 ) + 1

= 12 + 1 = 13

Hence degree of unsaturation = 13
