4. Among BeF₂, BF₃, NH₃ and CCI₄, the molecule with net dipole moment (polar) is: (you need to know the Lewis structure of those molecules) a) BeF₂ b) BF₃C) NH₃ d) CCI₄

5. According to VSEPR theory,

(a) the non-bonding electron pairs (lone pairs) only decide the structure of the molecule

(b) the bonding pairs only decide the structure of the molecule

(c) the lone pairs and bonding pairs both decide the structure of the molecule

(d) none of these

Answer 1

Answer #1

Q4 option C

reason:-

BeF2 is linear

and BF3 is trigonal planar

CCl4 is tetrahedral all cancel the bond polarity to give net dipole Zero

but in NH3 there is one lone that cause change in net dipole (polar)

Q5: Option (C)

in the VSEPR lone pair and bond pair both decides the shape of molecule

because there will be Some bond -bond pair repulsion and bond lone pair repulsion and lone lone pair repulsion exists that cause change in structure

Please give me thumbs up
