What is the number of double or triple bonds in the formula C3H8? What is the number of lone pairs Around each atom? And what is the number of single covalent bonds? I also need help with the formula C3H6O with the same questions!

For C3H8 I got 10 single covalent bonds. And for number of lone pairs I got 20-20=0e=0.
I did not get any answera for C3H6O

Would that be CH3CH=CHOH?

1 double
6 single
no lone pairs.
Check that.

C3H8 = Propane.

C3H6O = Acetone Propane.
I'm not sure if it is the same...

C3H8 is propane, right.

C3H6O is not acetone propane. What I drew for you is propene-1-ol

To determine the number of double or triple bonds in a molecule, you need to know the structure of the molecule or its Lewis structure. However, for C3H8, the formula indicates an alkane with three carbon atoms and eight hydrogen atoms. Alkanes have only single covalent bonds, so there are no double or triple bonds in C3H8.

For the number of lone pairs around each atom, we first need to find the number of valence electrons present in the molecule. Carbon has 4 valence electrons, and hydrogen has 1 valence electron. In C3H8, we have 3 carbon atoms and 8 hydrogen atoms.

The total number of valence electrons can be calculated as follows:
3 (carbon atoms) x 4 (valence electrons per carbon) + 8 (hydrogen atoms) x 1 (valence electron per hydrogen) = 12 + 8 = 20 valence electrons.

Next, we need to determine the number of electrons used in forming bonds. Each carbon atom forms four single covalent bonds with four hydrogen atoms. Therefore, the number of electrons used in forming bonds is 3 (carbon atoms) x 4 (bonds per carbon) = 12 electrons.

To find the number of lone pairs, subtract the number of electrons used in forming bonds from the total number of valence electrons. In this case, 20 (total valence electrons) - 12 (valence electrons used in forming bonds) = 8 lone pairs. However, keep in mind that lone pairs are typically assigned to individual atoms, not the entire molecule. Since C3H8 does not have any multiple bonds, we do not have to consider double or triple bonds with lone pairs.

Moving on to C3H6O, the formula suggests a molecule with three carbon atoms, six hydrogen atoms, and one oxygen atom. To determine the number of double or triple bonds, as well as the number of lone pairs, we need to know the molecular structure or Lewis structure of C3H6O. Without this information, we cannot provide a definitive answer for the number of double or triple bonds, nor the number of lone pairs in C3H6O.
