Density of gasoline is 0.737 g/mL and volume of tank is 13.0 gal.
Since, 1 US gal=3.78 L
Volume of tank in L will be:
Also, 1 L=1000 mL
Thus,
Mass of gasoline can be calculated as follows:
m=d×V
Here, d is density and V is volume thus,
Therefore, mass of gasoline will be .
Answer: There are 4 monofluoro derivatives of methylcyclopentane. Only 1 derivative has flourine atom attached to a primary carbon.
Explanation: The compound methylcyclopentane has 1-primary carbon, 4- secondary carbons and 1-tertiary carbon.
1) Primary carbon (1°): In this the carbon atom is attached directly to only one carbon atom.
2) Secondary carbon (2°): In this the carbon is attached directly to two carbon atoms.
3) Tertiary Carbon (3°): In this the carbon is attached directly to three carbon atoms.
The monofluoro derivatives are shown in the image below.
Structure B is the only derivative which has fluorine attached to primary carbon atom.
