A student has been asked to draw all the alkene isomers of C₄H₁₀ and draws the following. Which of the following statements about the student's diagram is correct?The student is wrong. The molecule on the right is just normal butane. Bending the end round doesn't change that.The student is wrong because she makes no reference to the numbers of protons and neutrons in the molecules.The student is wrong. There is another isomer called 1,2-dimethylethane.The student is correct and deserves a tuck-shop voucher.Question 6 of 22 Loading... 7.
