Std-10 Most Imp Ch 5 Gseb L-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:

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

Calculate the change in pH if 0.02 mol CH_(3)COONa is added to 1.0L of this solution. ltbRgt K_(a) of CH_(3)COOH = 1.8 xx 10^(-5) .

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