Answer:
They have fewer hydrogen atoms attached to the carbon chain than alkanes
Explanation:
Let's compare ethane (an alkane) with ethene (an alkene) and ethyne (an alkyne):
- Ethane's formula is C₂H₄, while ethene's is C₂H₄ and ethyne's C₂H₂.
As you can see, alkenes and alkynes have fewer hydrogen atoms attached to the carbon chain due to them having multiple bonds between the carbon atoms.
Answer:
Unit conversion between Rankine and Kelvin is linear.
Unit conversion between degree Celsius and degree Fahrenheit is linear.
Explanation:
Relation between rankine and Kelvin is

So, the plot between Rankine and Kelvin is a straight line with zero intercept and has a slope having value
.
Relation between degrees Celsius and degrees Fahrenheit is given by

So, the plot between degrees Celsius and degrees Fahrenheit is a straight line with slope
and negative intercept of
.
I don't think it's any of the above. Because there is two double carbon bonds and it belongs to an alkene, it should be an ethene molecule.
