The possible structures with 6-C Chain and 1 double bond i.e. the isomers are 2-methylhex-2-ene , 3-methylhex-2-ene , 4-methylhex-2-ene , 5-methylhex-2-ene , 2-methylhex-3-ene , 3-methylhex-3-ene , 4-methylhex-3-ene , 5-methylhex-3-ene , 2-methylhexene , 3-methylhexene , 4-methylhexene , 5-methylhexene .2-methylene hexane , 3-methylenehexane .
These all are functional group isomers.
<h3>isomers :</h3>same molecular formula but different physical and chemical properties .
<h3>Positional isomers :</h3>same molecular and chemical formula but different in position of the functional group .it is a structural isomerism .
<h3>functional isomers :</h3>same molecular formula but different functional groups attached to the main ring.

<h3>Answer:</h3>
812 kPa
<h3>Explanation:</h3>- According to Boyle's law pressure and volume of a fixed mass are inversely proportional at constant absolute temperature.
- Mathematically,
At varying pressure and volume;
P1V1=P2V2
In this case;
Initial volume, V1 = 2.0 L
Initial pressure, P1 = 101.5 kPa
Final volume, V1 = 0.25 L
We are required to determine the new pressure;
Replacing the known variables with the values;
= 812 kPa
Thus, the pressure of air inside the balloon after squeezing is 812 kPa
