Question

How many valence electrons does AI^+2 contain? 1 2 8 None of the listed What is the shape of carbon 2 in 2-fluorobutane? Sphere Trigonal planar Tetrahedral None of the listed What is the shape of the highest filled atomic orbital in Mg^+2? Sphere Trigonal planar Tetrahedral None of the listed Ethanol would have a characteristic IR stretch around Large round peak around 3300 cm^-1 Intense peak between 1700-1750 cm^-1 Both A and B Neither A nor B Ethanal would have a characteristic IR stretch around Large round peak 3300 cm^-1 Intense peak between 1700-1750 cm^-1 Both and B Neither A nor B Propanoic Acid would have characteristic lR stretch around Large round peak around 3300 cm^-1 Intense peak between 1700-1750 cm^-1 Both A and B Neither A nor B

Explanation / Answer

9.The outer electronic configuration of Al is : [Ne] 3s2 3p1

On removing wo electrons we get Al2+ : [Ne] 3s1

So the number of valency electrons are one(1)

So option (A) is correct

10.2-fluoro butane is CH3-CH(F)-CH2-CH3

1 2 3 4

Since the carbon -2 makes all bonds single (sigma) bonds so it undergoes sp3 hybridization thereby the shape of C-2 is tetrahedral.

Therefore option (C) is correct
