Solution

(a) Step-1 Condensed structural formula
Condensed structural formula is those formula which show order of atoms like a structural formula but are written in single line to save space and make it more convenient and faster to write out. These are also helpful to show if a group of atoms is connected to a single atom in a compound.
Or
Chemical formula without presence of σ or π bonds is called condensed formula.
condensed structural formula of the given compound can be drawn as:
HOCH2CH2CH(CH3)CH(CH3)CH3

Step-2 Bond line formula
A representation of molecular structure in which covalent bonds are represented with one line for each level of bond order. One single bond is represented with one line, two parallel lines show a double bond, and three parallel lines show a triple bond.

Or

Chemical formula without using carbon symbol in the total structure is called bond line formula.
Bond line formula of the given compound can be drawn as:


Final structure:condensed formulaHOCH2CH2CH(CH3)CH(CH3)CH3
Bond in formula


(b) Step-1 Condensed structural formula
Condensed structural formula is those formula which show order of atoms like a structural formula but are written in single line to save space and make it more convenient and faster to write out. These are also helpful to show if a group of atoms is connected to a single atom in a compound.

Or

Chemical formula without presence of σ or π bonds is called condensed formula.
condensed structural formula of the given compound can be drawn as:
HOCH(CN)2

Step-2 Bond line formula
A representation of molecular structure in which covalent bonds are represented with one line for each level of bond order. One single bond is represented with one line, two parallel lines show a double bond, and three parallel lines show a triple bond.

Or

Chemical formula without using carbon symbol in the total structure is called bond-line formula.
Bond line formula of the given compound can be drawn as:


Final structure: condensed formulaHOCH(CN)2
Bond line formula
