Std-10 Most Imp Ch 4 Gseb L-3

List two most common STDs.

Most common bacterial STD is:

For the process, CH_(3)OH(l) to CH_(3)OH_(g), DeltaG^(@)=4.30 kJ //mol at 25^(@)C . What is the vapour pressure of Ch_(3)OH(l) at 25^(@)C "in mm Hg"

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

The least and most stable resonating structure respectively are: (1) CH_(2)=CH-CH-CH-C-CH_(3) (2) CH_(2)=CH-CH-CH=C-CH_(3)O^(Theta) (3) CH_(2)-CH-CH=CH-C-CH_(3) (4) CH_(2)=CH-CH=CH-C-CH_(3) (А) 1,4 (В) 2,3 (С) 4,1

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