Interpretation Introduction
Interpretation:
Lewis structure of CH3OH has to be drawn.
Concept Introduction:
Electron dot structure also known as Lewis dot structure represents the number of valence electrons of an atom or constituent atoms bonded in a molecule. Each dot corresponds to one electron.
Explanation of Solution
Total valence electrons in CH3OH is,
(valence e- on C )+ (valence e- on H)+(valence e- on O) = 4+4(1)+6 = 14
Accordingly Lewis structure of CH3OH is drawn which shows 14 electrons in the molecule including bonding and non-bonding electrons.

Interpretation Introduction
Interpretation:
Lewis structure of CH3CH2OH has to be drawn.
Concept Introduction:
Electron dot structure also known as Lewis dot structure represents the number of valence electrons of an atom or constituent atoms bonded in a molecule. Each dot corresponds to one electron.
Explanation of Solution
Total valence electrons in CH3CH2OH is,
(valence e- on C )+ (valence e- on H)+(valence e- on O) = 2(4)+6(1)+6 = 20
Accordingly Lewis structure of CH3CH2OH is drawn which shows 20 electrons in the molecule, including bonding and non-bonding electrons.

Different types of alcohol groups
Alcohol and its reaction:
8. Combing two alcohol molecules below and completing the reaction with
Product .( Hint Reaction called etherification as ether is formed and name the
ether once you complete the reaction.
Hint.:
R-O-H+H-O-RR-O-R
Do the reaction:
CH₂OH + CH₂OH---→
+ H-O-H
9. Write the reaction of formation of alcohol from alkene by adding water:
Addition reaction also called hydration reaction as we are adding water
which occur always in presence of acid
Hint: Break the double bond and add H and OH if symmetrical then
add anywhere if unsymmetrical then follow Markovnikov rule H
should go to that double bone carbon which has more hydrogen
CH2=CH2 + H₂O-→
