Ifosfamide is a pharmaceutical used in the treatment of testicular cancer. Identify the number of sigma bonds in this structure. CH2 .N. CH2

Fill in any nonbonding valence electrons that are missing from the following structures.

The amount of UVA radiation hitting a surface at sea level in a lightly clouded day is about 70W/m2 . About half of that can be absorbed by the skin. A typical carboncarbon bond requires 348 kJ/mol to break. A person lies on the beach for about 1 hour without sunscreen (i.e. fully exposed to UVA radiation). Estimate the number of C-C bonds broken in this person’s back (about 0.18 m2 ) over that period. Assume that the average wavelength of UVA is 335 nm.
