Answer:

Yes, you can #H# atoms, add, except...

Explanation:

H atoms can be added to all carbons except, #=C=#, which #C# has already bonded with #4 H# atoms, which means that, #H# can't be added again..

In Organic Chemistry, Carbon, C has the ability to bond with only 4 Hydrogen Atoms, #H..#

#"C = C - C = C - C = C = C - OH"# Where each #= or -# represent the hydrogen Carbon is bonded with..

Also...

For #"C = C"#.... Carbon, #C# has the ability to have only #2 H#, attached to it, since they already have #2 H# each..

Hope you understand!

Answer:

No. See explanation.

Explanation:

Carbon can make 4 bonds. From those bonds we can see that (counting from left to right):

  • first atom uses 2, so it can have 2 atoms of hydrogen,

  • second, third, fourth and fifth use 3 (you count bonds both left and right from the atom), so you can add one hydrogen atom to each carbon,

  • sixth atom uses four, so you cannot add anything here,

  • last atom uses 3 bonds, so you can add one hydrogen atom here.

Finally the fomula would be:

#CH_2 = CH-CH=CH-CH=C=CH-OH#
