###### Problem Details

Consider a 1.00 L solution of 0.150 M HCN (Ka = 4.9 * 10−10); Assume carbon is the central atom.

Indicate whether each statement is true or false.

A. There are more HCN molecules in the solution than CN ions

B. The acid reaction (corresponding to Ka) would have a ΔG° < 0

C. Adding 0.150 moles of a strong base to this solution would make a buffer

D. HCN is polar and has a linear shape

E. The best Lewis structure would have a single bond and triple bond on C

F. HCN would exhibit hydrogen bonds with water
