Reset Help all atoms, bonds, and A skeletal structure shows nonbonding electrons A Lewis structure shows only the bonds between carbon atoms and the bonds between carbon and heteroatoms all atoms and bonds, but no nonbonding electrons all atoms and electrons, but no bonds only the bonds between carbon atoms and the bonds between carbon and hydrogen atoms only the bonds between carbon atoms

Answer 1

Answer to question 1,

A skeletal structure of a chemical compound is the connected series of lines of atoms bonded in that compound. It gives us details about bonding arrangement of atoms, their charge , presence of branching and position of functional groups present. But non bonding electrons present in atoms are not shown. And only bonds between C atoms and bonds between C atom and hetero atoms is drawn. C-H bonds are not shown.

A Lewis structure of a chemical compound is the representation of all bonds between atoms present in molecule and non bonding electrons as set of electrons (assuming each dot as one electron). It clearly shows the bonds (bond pairs of electrons) present and lone pair electrons present in each atom.

An example of both structures is given below,

An example of both structures is given below, Lewi's electronic dot structure But each bond pair can be represented as a bond. Hence the answer is, A skeletal structure shows

But each bond pair can be represented as a bond.

Hence the answer is ,

A skeletal structure shows - only the bonds between carbon atoms and the bonds between carbon and hetero atoms.

A Lewis structure shows - all atoms, bonds and non bonding electrons.

Answer to question 2,

A condensed structural formula for an organic molecule is a long chain type representation of molecule with all atoms. It contains bonds between C atoms and bonds between C and hetero atoms. But it do not show C-H bonds and non bonding electrons of atoms in that molecule.

Hence the answer is C
