dear student,


Alkanes experience inter-molecular Van der Waals forces. The stronger the force, the greater will be the boiling point of the alkane.


As branching increases, the surface area of the molecule decreases which results in a small area of contact. As a result, the Van der Waals force also decreases which can be overcome at a relatively lower temperature. Hence, the boiling point of an alkane chain decreases with an increase in branching.

Diboorane b2h6 can be prepared by the reaction 3NaBH4 + 4BF3 GIVES 3NaBF4 + 2B2H6 If the reaction has 70 % yield ,how many moles of NaBH4 should be used with excess BF3 in order to obtain...
 
 
3NaBH4 + 4BF3--------3NaBF4 + 2B2H6 1 mole of b2h6 produces 1.5 mole of nabh4 .2 mole of b2h6 will produce (1.5*10*10)/14=10.7 mole sice the yield is 70%
