Hydrogen carbons can be broadly categorized into four types: saturated, unsaturated, cycloakanes and aromatic hydrocarbons. Saturated hydrocarbons are made of single covalent bonds between carbon atoms while unsaturated hydrocarbons have one or more double or triple bonds shared between the adjacent carbon atoms. Cycloalkanes refer to hydrocarbons that contain one or more carbon rings while aromatic hydrocarbons are compounds with alternative single and double bonds between carbon rings
Saturated hydrocarbons are also known as alkanes or paraffins. They are either found as branched or linear specie and form the basis of most petroleum fuels. An example of this type of hydrocarbon is methane, which is also the most basic type of alkane. Other examples include butane, pentane and propane. Saturated hydrocarbons have the general formula CnH2n+2.
Unsaturated hydrocarbons can either be alkenes or alkynes. Alkenes refer to compounds with at least one carbon-to-carbon double bond, while alkynes have a minimum of one carbon-to-carbon triple bond. Unsaturated hydrocarbons may also come with both double and triple bonds. In such instances, the compound is named with a prefix preceding the suffix ene or yne depending on the position of the bond, for instance 2 4-pentadiene. Unsaturated hydrocarbons are highly reactive with water, hydrogen halides, alcohols, and elemental halogens. Alkynes are, however, more reactive than alkenes.Learn More

Novels, also termed "fiction," may be categorized as literary, mainstream or genre. Literary novels focus on characters' internal experiences and personal journeys. They are often critically acclaimed for both subject matter and writing style. Genre fiction follows a specific storytelling pattern, and mainstream novels appeal to a wide audience.Full Answer >
Leaves can be categorized according to shape, edge, the pattern of the veins, and by the way they are arranged on the stem. Common shapes include: "lanceolate" or spear-shaped; "ovate" or egg-shaped; "acicular" or needle-shaped; "cordate" or heart-shaped; "linear" or strip-shaped; and "hastate" which are broad and round on the bottom edge but come to a sharp point on top.Full Answer >
Acids come in two primary types, which are strong and weak. The primary difference between strong and weak acids is that strong acids have the ability to fully dissolve or ionize when placed in solutions while weak acids only partially dissolve when exposed to solutions.Full Answer >
