Std-10 Most Imp Ch 2 Gseb L-5

Which of the following should be most volatile? I) CH_3 CH_2 CH_2 NH_2 II) (CH_3)_3 N III) IV) CH_3 CH_2 CH_3

A : When C_(2) H_(5) - O- CH_(3) is reacted with oen mole of Hl then C_(2)H_(5)OH& CH_(3) l is formed . R : It is S_(N)1 reaction

List two most common STDs.

Most common bacterial STD is:

The equilibrium constant for the reaction: CH_(3)COOH(l) + C_(2)H_(5)OH(l) iff CH_(3)COOC_(2)H_(5)(l)+ H_(2)O(l) has been found to be equal to 4 at 25^(@)C . Calcuclate the free energy chnage for the reaction.

CH_(3)CH_(2)l reacts more rapidly with strong base in comparison to CD_(3)CH_(2)l . Explain

Select the most stable carboncation from the following: CH_(3)^(+),(CH_(3))_(2)CH^(+),CH_(3)CH_(2)^(+),(CH_(3))_(3)C^(+)
