Question

difference between- 1]Alkane and Alkene 2]Artria and ventricies

Answer 1

1.

Alkanes	Alkenes
Alkanes are hydrocarbons that consists of only single covalent bond . They can be straight chain or branched chain. General Formula : CnH2n+2 for eg : CH4 ,C2H6 (CH3-CH3), CH3-CH2-CH2-CH3	Alkenes are hydrocarbons that contain atleast one double covalent bond that is -C=C-. General formula: CnH2n For eg : CH3-CH=CH2 CH3-CH2-CH=CH2

2.

Atria	Ventricles
These are upper two chambers of heart	These are lower two chambers of heart
They are less muscular and smaller	They are more muscular and larger
They have thin walls	They have thick wall
They receive blood	They pump blood
