Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. H3C H₂C a O ao H₂ b b Hc N CH₂ Submit Answer OC₂H5 The number of unshared pairs at atom a is The number of unshared pairs at atom bis The number of unshared pairs at atom cis The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom cis Retry Entire Group 9 more group attempts remaining V 0 1 2 3 4 Previous Email Instructor Next Save and Exit
