Fiend the hydrocarbon A knowing that:
- it has NE=1;
-it can react whit Br2 in CCl4(which means that it has double bound) and whit the weak alkaline solution KMnO4(idk what it means ,if it say weak maybe whit h2o+Kmn04)
-in hydrogenations(means +H2) whit Ni it makes an  saturated compound whit the formula C5H12;
-1 moll of hydrocarbon A consumes 0,5 L solution K2CR207 on concentration 2M ,mixed whit H2SO4(idk what it means)

I am thinking that if it has NE=1 it is a alkenand if the hydrocarbon +h2=a compound whit c5h12 formula then the hydrocarbon is c5h12  and it has double bound
So if i am right the compound has to have the formula c5h12 ,it has double bound  and NE=1

i think its 3 methyl 1 butene because it has double bound ,it has NE=1 which means its an alken and +H2 it makes c5h12

I think your answer is wrong.

Think about the reaction with acidified K₂Cr₂O₇.

How many moles of K₂Cr₂O₇ react with 1 mole of the alkene? What does this tell you about the oxidation reaction - remember, K₂Cr₂O₇ is a 6 electron oxidant.

can you explain more? i am sure that the compound i wrote is good until that point

Again:

If you demonstrate effort, you will get all the help you need.
