Protonation question
Hi,
I was wondering if someone could let me know why it is the O that gets protonated instead of a C? Thanks in advance!!#

Oxygen has a lone pair of electrons and is electronegative.

Thank you!! I wasn't sure if an element being more electronegative in general meant it accepted a hydrogen more readily...

The lone pair of electrons is the most important factor.

Ah okay thanks! If there was also a NH2 group, then would the O still be the one that is protonated because though both N and O have lone pairs, O has a bigger electronegativity?

They will both be protonated
