WebWith B r 2 − H 2 O, phenol gives 2,4,6- tribromophenol but with B r − C S 2 , it gives 4-bromophenol as the major product. Because In water ionization of phenol is enhanced but in C S 2 , it is greatly suppressed. Hence, both Assertion and Reason are correct and Reason is the correct explanation for Assertion. お詫び 菓子折り 郵送 手紙WebWhat is the major product of the reaction between 2-methylbut-2-ene and Br2 in H2O? arrow_forward The addition reaction of an acid (HBr) to an alkene (CH3CH=CH2) follows … お詫び 訪問 アポ 電話WebSolution Verified by Toppr Correct option is C) Phenol when treated with Br 2 water give polybromoderivative in which all H- atoms at ortho and para positions with respect to −OH … pasticceria cominoWith dilute nitric acid: Phenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol.
