Chemical Bonding

Question 1

Name of H2S2O8

Answer 1

Peroxydisulphuric acid
Or
Marshals acid

Question 2

Answer 2

Cyanic acid
&
Thiocyanic acid

Question 3

Hybridization of –
NO2
&
ClO2

Answer 3

Sp2 (forms diamer)
&
Sp2 (delocalise electron to form 3 electron bond

Question 4

Structure of allene

Answer 4

CH2=C=CH2

Question 5

Max no of atom in a plane in allene

Answer 5

5

Question 6

No of pπ-dπ bond in XeO3

Answer 6

3

Question 7

Why Hybradisation of Ch3 is sp2 and CF3 is sp3 ?

Answer 7

because F is present which is very electronegative element so it attracts an unpaired electron towards itself and add it in hybridization due to which hybridization get shift from sp2 to sp3.

Trick😄: # if central atom has odd electron partial +ve charge (on central atom) then odd electron takes part in hybradisation
And if central atom is more EN then it don’t take part in hybradisation.
#🧐if central atom has both lone pair and odd elctron then odd electron do not take part in hybradisation.. 🫷

Question 8

Charge on 1 electron in esu
