Indicate which, if any, of these orbitals have identical ener-
gies from symmetry considerations. Show the number of
electrons occupying each w MO in the ground state, and
indicate whether either or both of the molecules are para-
magnetic. Assume that the C atoms in the allyl radical are
all sp? hybridized.

A typical 1"B – 'H bond has a stretching frequency of 2400 cm1. Based on your understanding of
isotopic effects on vibrational frequencies, and their connection to bond strength, rank the B - H bonds
from weakest to strongest. Consider the most common isotopes of the B- H bonds highlighted below.
Make sure to explain your ranking.

Since carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet. Draw an isomer of C5H11Cl that would be expected to have four resonances in its 13C NMR spectra.arrow_forward
