In the case of carbon (C), it typically forms 4 bonds and has 0 lone pairs.
In methane (CH4), the central carbon atom does not have any lone pairs of electrons. Instead, it forms four single covalent bonds with the four hydrogen atoms around it.
0, Cbonds to 3 H and to C. Second C triple bonds to N . H H C-C---N: H
There is 1 lone pair around the central C atom
A molecule of CO2 contains one atom of Carbon and two atoms of Oxygen forming a compound or molecule (pure substance) of Carbon dioxide. In order to find out how many lone pairs are in the molecule, you have to look at how many valence electrons you're working with. Carbon has 4 and Oxygen has 6 per atom x 2 giving us 12. 12+4 = 16e. Since carbon has 4, it must share a double bond with oxygen on each side to form a stable structure. Since this is a linear shape and the charges are facing away from each other, the bond is Nonpolar._ _|O=C=O|The answer to your question is four
CO2 has a linear molecular geometry with a triple bond between the carbon and oxygen atoms and two lone pairs on each oxygen atom. The Lewis structure would show two double bonds between the carbon and oxygen atoms, with each oxygen atom having two lone pairs around it.

Cytosine (C) always pairs with guanine (G), and thymine (T) always pairs with adenine (A). This forms the complementary base pairs in DNA, where CG and TA are the base pairs.
GC base pairs are more stable than AT base pairs because they have three hydrogen bonds holding them together, while AT base pairs have only two hydrogen bonds. This extra bond in GC pairs makes them stronger and more difficult to break apart.
Hydrogen bonds hold matched nucleotides together in DNA. Specifically, adenine pairs with thymine through two hydrogen bonds, and cytosine pairs with guanine through three hydrogen bonds. These hydrogen bonds contribute to the stability of the double helix structure of DNA.
The answer is 2 since the Oxygen is double bonded with a carbon O=C
A bonds with TG bonds with C
The question is not answerable. There is NO central atom in C2H2 (ethyn) and there's NO lone pair. All electrons are covalently shared in pairs: three pairs between C and C, one single pair in each C and H bond.
The bonds that hold together DNA are hydrogen bonds between complementary base pairs: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). These base pairs form the "rungs" of the DNA double helix, which is stabilized by sugar-phosphate backbones of the DNA strands.
