Quick question about HNMR

For t-butyl alcohol, how many peaks should be present? I thought it would be three. One for the hydroxyl group, one for the 9 equivalent H on the methyl group and one with 10 spilts for the carbon with no H attached (due to the 9 H of the methyl group). Is this right? Or am I missing something here?

The last part is incorrect. You would only have two signals in all. 1 singlet for the hydroxy H as it contains no nearest neighbors 0 +1. And another signal for one of the 9 Hs as they are all equivalent. The central carbon has no Hs on it and therefore does not produce a signal regardless of whether or not it has any neighbors

ohhh ok. That makes sense. Thank you for clarifying that for me. When I saw two peaks I couldn't understand why.

Np. Get this down cold as this is basically a free point on the real thing thing
