How many hydrogen atoms does carbon have?

Answer 1

There are a base four carbons, which makes the base alkane butane. The formula for a hydrocarbon is CxH(2x+2). However, there are two double bonds, so that removes two hydrogens. The total number of hydrogens is 8.

Answer 2

if you're talking about C=C-C=C :

1st the = symbol does not mean equals but a double bond between 2 atoms, and the - symbol means a simple bond between 2 atoms.

The compound you are looking for is an hydrocarbon as it contains only Carbon and Hydrogen. As you have 2 double bonds, it belongs to a family called dienes.

When you want to complete the formula of a hydrocarbon compound, you have to make sure each carbon has 4 bonds. Here the 1st Carbon has only 2 bonds to the 2nd Carbon and thus needs 2 Hydrogen atoms. The 2nd Carbon atom has 3 bonds (2 with the 1st one, and 1 with the 3rd one) and thus need 1 Hydrogen atom. Similarly, 3rd and 4th carbons need 1 and 2 hydrogen atoms respectively.

So, you will have 2+1+1+2, that is 6 Hydrogen atoms with these carbons. The molecular formula is (C4H6) and this compound is called butadiene.

Short structural formula: CH2=CH-CH=CH2

Answer 3

C=C-C=C

A carbon atom has 4 electrons in the outer shell and it can have 4 covalent bonds.

The Carbon atoms on either side already have two bonds (with carbon), so each of them can have two more Hydrogen atoms attached to them. = 4

The two carbon atoms in the middle have three bonds each (with carbon) and those two can have one more Hydrogen per each. = 2

Altogether, there can be 6 hydrogen atoms, if and only if it is a Carbon and Hydrogen only atom. :-)

N.B.

When writing a question, it would sound a smart way to say "equals", but don't use the "equal" when you speak, because it is not an equal sign. That means, there are two electrons shared between the two atoms.

Answer 4

Six H atoms: CH3-O-CH3

Remember as rule of thumb: C atoms are tertra-valent (4) and O are bivalent (2)

Answer 5

None. Carbon and hydrogen are two different elements.

Answer 6

Your carbons will al have to have hydrogens. Each C has 4 bonds spaces. There is space for 3 hydrogens on the first carbon and 2 on the second. C3C2OH
