4 ) In each pair of bonds, predict which is shorter. Explain why. I need help with 4C
(4. In each pair of bonds, predict which is shorter. Explain why.
A. Si-N or Si-O
Si- 0
when we move left ho right in a period
bond is shortcst
in comparison to Si-N bond, blC
size, itd.
B. Si-O or C-O
Co bond is shor test in comparilon to Si-0 bond blc uwhen we mave
top to bo tHom in agroup, theretore the cltomic size ↑
CI
C=
or C=C
5. Compare the Carbon-Oxygen bond lengths in the formate ion (HCO2), in methanol (CH;OH), and carbonate ion
(CO,?-). In which species is the Carbon-Oxygen bond predicted to be longest ? In which is it predicted to be
shortest ? Explain each case. (Hint: Draw a stable Lewis structure for each ion, and compare their C-O bond
order)
