# Mechanism of hydrolysis of acyl chlorides

The following mechanism for acyl chloride hydrolysis was given by my professor :

However I do not understand why in the second step, oxygen has a partially negative charge, should it not gain a positive charge as it is bonded to three atoms, furthermore shouldn't the $$\text{O}-\text{H}$$ bond breaking homolytically form a $$\text{H}^-$$ ion and not a proton?

Should the arrow be reversed in the second step?

• Do not confuse real charge with formal charge. – Zhe Apr 15 at 3:10
