31

the chemical formula CH4 has 4 hydrogen atoms and forms a single covalent bond with carbon atom by sharing a pair of electrons, which results in a filled outermost shell is an example of

carbon atoms forming up to four covalent bonds with other atoms to satisfy the octet rule

32

we often use these in our daily lives for fuels

hydrocarbons

33

although most biological molecules contain atoms besides carbon and hydrogen, many of them have regions that resemble

hydrocarbons

34

name the variations in carbon skeletons

length, branching, double bonds, and rings

35

the many covalent bonds between the atoms in ________ store a great amount of energy, which is released when theses molecules are______

hydrocarbons, burned (oxidized)

36

the simplest hydrocarbon molecule, with a central carbon atom bonded to four different hydrogen atoms

Methane an excellent fuel

47

Are formed by successive bonds between carbon atoms and may be branched or unbranched

hydrocarbon chains

48

when a carbon forms single bonds with other atoms, the shape is

tetrahedral

49

when 2 carbon atoms for a double bond the shape is

planar or flat

50

do single bonds rotate

yes

51

do double bonds rotate

no the atoms are locked in place

52

consist of linear chains of carbon atoms

aliphatic hydrocarbons

53

consists of closed rings carbon atoms

aromatic hydrocarbons

54

these structures are found in carbon double bonds, examples are benzene to include some amino acids and cholesterol and it derivative, hormones includes estrogen and testosterone

rings

55

beta-carotene is an example of an

hydrocarbon

56

cyclopentane, cyclohexane, benzeene, and pyridine ware examples of

carbon forming five and six membered rings
