Question

Question 6 3 pts negative than nitrogen (N) means that in a CN bond, the O shared electrons are closer to the C atom than to the N atom. O shared electrons are closer to the N atom than to the C atom. C atom takes the electrons from the N atom forming C-and N: O N atom takes the electrons from the C atom forming C' and N D Question 7 3 pts A polar covalent bond is created when O a metallic element reacts with a nonmetallic element. O two atoms share their bonding electrons unequally O two atoms share three or more electrons O two atoms of the same element form double or triple bonds.

Explanation / Answer

ans)

6)

from above information that

the answer is

Shared electrons closer to the Nitrogen and C+ and N-

because here Carbon belongs to the IV A group of element and the Nitrogen belongs to the V A group of element.

In the periodic table from left to right the electronegativity increases, That means the Nitrogen is the more electronegative atom than the Carbon.

In the C-N the shared pair of electrons are moves towards the Nitrogen atom due to more electronegativity of the Nitrogen as a result of this can get partial positive charge on the carbon and partial negative charge on the Nitrogen.

If heterolytic cleave takes place, The carbon gets the positive charge and Nitrogen gets negative charge.

7)

A polar covalent bond is created when?

a. a metallic element reacts with a nonmetallic element

--> False,

because it is typically made by nonmetals

b. two atoms share their bonding electrons unequally

--> true,

because it is an unequal share of electrons

c. two atoms share three or more electrons

--> false,

because this can be done with tdifferent set of electrons

d. two atoms of the same element form double or triple bonds

--> false,

because no need to double / Triple bonding
