What is the bond order for the carbon-nitrogen bond in acetonitrile, CH3CN? 2.2.0 03.0.5 C. 3.0 d. 1.5 0.1.0
marin [14]

Answer:

C. 3.0

Explanation:

Bond order is number of the bonding pairs of the electrons between two atoms.

For CH_3CN,

The total number of the valence electrons  = 2(4) + 1(5) + 3(1) = 16

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,  

The Lewis structure is:

          H

           :                  

H   :    C   :   C   :  :  :   N :

           :

          H

Bond pairs between C and N is 3

<u>So bond pair is 3.</u>

How many protons do you think are dissociable from propionic acid and butyric acid? Explain your reasoning.
RSB [31]

Answer:

One

Explanation:

The formulas for the two acids are CH₃CH₂COO-H and CH₃CH₂CH₂COO-H.

The key factors to consider are the polarities of the C-H and O-H bonds.

A. C-H bonds

The difference in electronegativity is ΔEN =|2.55 - 2.20| = 0.35.

This difference of so small that we usually consider the C-H bond to be nonpolar.

It is extremely unlikely that a C-H bond will dissociate onto ions.

B. O-H bonds

The difference in electronegativity is ΔEN =|3.44 - 2.20| = 1.24.

Thus, an O-H bond is highly polar covalent — the bond has about 32 % ionic character.

It is much more likely that an O-H bond will go all the way and dissociate onto ions.

RCOOH + H₂O ⇌ RCOO⁻ + H₃O⁺

The Kₐ for an O-H bond is about 10⁴⁶ times that of a C-H bond.

Only the O-H bond of a carboxylic acid will dissociate,
