Which one of these has the smallest # of hydrogen atoms?
a) Butyne
b) Butane
c) Butyne
d) Cyclobutane
Is the answer c)?
How is (a) different from (c) ?
Googling the compound names will get you the formulas
**Sorry, c) was supposed to be butene.
So it should be a) correct?
Butyne has 6 H's
Butane has 10 H's
Butene has 8 H's
Cyclobutane has 8 H's
Yes, a is correct
a) Butyne (CH3CH2CCH) 6H
b) Butane (CH3CH2CH2CH3) 10H
c) Butene (CH3CH2CHCH2) 8H
d) Cyclobutane (CH2CH2CH2CH2) 8H
so agreed a)
Note that there is a learning point here in that there is an equivalance between a ring (in cyclobutane) and a double bond. So we can talk in terms of 'double bond equivalents'.
Thank you!
To determine which compound has the smallest number of hydrogen atoms, we need to examine the molecular formulas of each compound.
a) Butyne: C4H6 - This compound has 6 hydrogen atoms.
b) Butane: C4H10 - This compound has 10 hydrogen atoms.
c) Butene: C4H8 - This compound has 8 hydrogen atoms.
d) Cyclobutane: C4H8 - This compound also has 8 hydrogen atoms.
Based on the number of hydrogen atoms, the compound with the smallest number is option (a) Butyne, which has only 6 hydrogen atoms. So, the correct answer is a).
