Which molecule is largest? hydrogen carbon dioxide ammonia maltose

maltose

Explanation:

If we intend to determine the largest molecule, then we must look at the relative molecular mass of each molecule because the larger the molar mass, the larger the molecule.

Hydrogen =2 gmol-1

Carbon dioxide = 44 gmol-1

Ammonia = 17 gmol-1

Maltose= 342.3 g/mol

Hence maltose is the largest molecule among the options.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
