Answer:
C. 3.0
Explanation:
Bond order is number of the bonding pairs of the electrons between two atoms.
For
,
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>
No, ammonium chloride in water is not a physical reaction. It is a chemical reaction. Hope this helps!
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,
