ethane-1,2-diol is used as antifreeze. suggest a reason why it is preferred to methanol which was formerly used for this purpose.

The reason is higher boiling point and lower toxicity.

Is it less flammable as well?

It is still pretty toxic, right?

It is still fairly toxic, but much less so than methanol.  Methanol is VERY volatile and is easily vaporized.  Inhalation of this vapor is not a good thing.  Ethane-1,2-diol is much less volatile, so it won't vaporize as easily and there's less chance that somebody would inhale it.

Volatile, flammable liquid + hot engine + sparks = disaster 8)
