This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Four. They are methyl-propene (or isobutene), cis 2-butene, trans 2-butene and 1-butene (or simply butene).

Can there be any cyclic isomers for this compound?

Led Tasso - 7 years, 6 months ago

Yes, but he specifies what kinds of isomers he wants (alkenes). C4H8 would be a cyclic alkane.

Guilherme Dela Corte - 7 years, 6 months ago

@Guilherme Dela Corte – And those would be cyclobutane and methyl cyclopropane.

Siyu Bu - 7 years, 6 months ago

@Siyu Bu – Yes, but he specifies what kinds of isomers he wants (alkenes).

Guilherme Dela Corte - 7 years, 6 months ago

@Guilherme Dela Corte – Yeah yeah totally agreed with you just was trying to add sth.:-)

Siyu Bu - 7 years, 6 months ago

@Guilherme Dela Corte – however, cycloalkane is an isomer of alkene with same molecular formula. i think we have to consider all types of isomerism.

Quite fast at chemistry. Good!!!

SHUBHAM KUMAR - 7 years, 6 months ago

Isn't this a question of NSEJS???

Jitesh Mittal - 7 years, 6 months ago

Yes,how much you are scoring in NSEJS ?

Divyansh Singhal - 7 years, 6 months ago

140 and if this answer ( I have done 4) is correct then 143 and what about you... We will have a common cutoff of Rajasthan...

Arent u the one who got state rank 1 in IMO??

Jitesh Mittal - 7 years, 6 months ago

C4H8 have 4 isomers

Shobhit Mishra - 7 years, 6 months ago

C4H8 have 3 isomer, they are : H2C = CH – CH2– CH3 1-butena H3C - CH = CH– CH3 2-butena H2C = C – CH3 2-metilpropena I CH3

Syarifuddin Hidayatullah - 7 years, 6 months ago

What about cis/trans isomers of 2-butene? Also I think you've wronged when writing methyl-propene's formula.

Guilherme Dela Corte - 7 years, 6 months ago

but-1-ene, but-2-ene, cyclobutane, methylcyclopropane, cis-2-butene, trans-2-butene

Cody Martin - 7 years, 6 months ago

He clearly specifies: he only wants the alkenes.

Guilherme Dela Corte - 7 years, 6 months ago

oh sorry there are 5 isomers then but-1-ene, but-2-ene, 2-methyl propene, cis-2-butene, trans-2-butene,

Cody Martin - 7 years, 6 months ago

which one ..structural or all?

akshu gupta - 7 years, 6 months ago

6 including the 2 cyclic isomers
