Question

QUESTION 4 2 points Save Answer Which reagents are involved in this reaction? ВНз/Н202 excess BH3 Нзо+ aldehydes QUESTION 5 2 points Save Answer What is the basis for Markovnikov's rule? Tetrasubstituted alkenes are most stable Torsional strain is decreased Higher order carbocations are more stable and therefore favored Steric strain is decreased

Answer 1

Question 4 ) terminal alkynes are converted to aldehyde through Hydroboration reaction

So correct reagent is BH_{3 /} H₂O_{2 .}answer is ( 1 )

Question 5 ) basis of Markovnikov ‘ s rule is stability of carbocation. Since higher order carbocations are more stable due to induction and Hyperconjugation. So correct answer is option ( 3 ).
