What is the iupac name for the following compound? question 10 options: 1-methyl-3-cyclohexene methylcyclohexene 5-methylcyclohexene 1-methyl-4-cyclohexene 4-methylcyclohexene

Explanation:

The compound is an alkene (cycloalkene), with a methyl group as substituent (it substitutes one hydrogen in the carbon chain).

The IUPAC's rules state that the location of the carbon-carbon double bond in the structure is indicated by specifying the number of the carbon atom at which the C=C bond starts, assigning the lowest possible number to the double bond: this in this case is number 1.

Cyclohexene is the main chain and mehtyl is a substituent, as already said.

So, the name 1-methyl-3-cychlohexene is not valid (position 1 is for the carbon-carbon double bond).

The name methycyclohexene is not valid because it is not telling the position of methylgroup.

The name 5-methylcyclohexene is not valid because the position five should be named 2 in the cyclohexene (you must use the smallest number), so the name should be 2-methyl... instead of 5 methyl...

1-methyl-4cyclohexene is not valid because, as said, the position 1 is reserved for the carbon-carbon double bond.

Only 4-methylcyclohexene is a valid name.

The file attached shows the structure. I have added numbers on the carbons of the main chain to show you how that the methyl group is in the positiion number 4.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
