Given :
2.5 mole of Sulfuric acid
.
To Find :
Mass of sodium hydroxide will completely neutralize 2.5 mol of sulfuric acid
Solution :
Let us assume volume of water be 1 L .
Now , we know , to neutralize 1 mole of sulfuric acid we need 2 moles of NaOH .
So , for 2.5 mole sulfuric acid required 5 mole of NaOH .
Moles of NaOH ,
Molecular mass of NaOH , M.M = 58.44 g/mol .
Mass of 5 moles of NaOH :

Hence , this is the required solution .
We need the IUPAC name of the given compound.
The IUPAC name is: Hexan-3-imine.
The molecule has six carbon atoms in its skeleton. C=NH bond is attached to the skeleton at 3-position.
The functional group present in this molecule is imine (C=NH).
