Hi, I'm trying to name this molecule so I can look it up online, but I'm not exactly sure how to do it... So it's a 4 carbon chain. On the 2nd carbon, there is a ketal protecting group--there are 2 O's connected to the C to form a 5 member ring. On the 4th carbon of the chain, there are 2 phenyls and 1 OH group. Anyone know how to call this?
