What are the 10 alkanes?

Why are alkanes unreactive?

Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from their reaction with oxygen in the air – which we call burning or combustion.

What is the general formula of alcohol?

The general molecular formula for alcohols is CnH2n+1OH. Alcohols are all derivatives of hydrocarbons in which one or more of the hydrogen atoms in the hydrocarbon have been replaced by a hydroxyl group. The hydroxyl group is also responsible for imparting certain chemical and/or physical properties to the compound.

What is the molecular formula for alkane?

Alkanes are organic compounds that consist of single-bonded carbon and hydrogen atoms. The formula for Alkanes is CnH2n+2, subdivided into three groups – chain alkanes, cycloalkanes, and the branched alkanes.

What is the 3 types of alcohol?

In chemistry, an alcohol exists when a hydroxy group, a pair of oxygen and hydrogen atoms, replaces the hydrogen atom in a hydrocarbon. Alcohols bind with other atoms to create secondary alcohols. These secondary alcohols are the three types of alcohol that humans use every day: methanol, isopropanol, and ethanol.

How are alkanes named?

The names of all alkanes end with -ane. … Alkanes with unbranched carbon chains are simply named by the number of carbons in the chain. The first four members of the series (in terms of number of carbon atoms) are named as follows: CH4 = methane = one hydrogen-saturated carbon.

What is general formula of aldehyde?

aldehyde ăl´dəhīd [key] [ al cohol + New Lat. dehydrogenatus =dehydrogenated], any of a class of organic compounds that contain the carbonyl group , >C=O , and in which the carbonyl group is bonded to at least one hydrogen; the general formula for an aldehyde is RCHO, where R is hydrogen or an alkyl or aryl group.

What is the general formula of alkanes and alkenes?

Alkenes and alkynes are called as unsaturated hydrocarbons. Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms. Alkenes have the general formula CnH2n.

Is alcohol acidic or basic?

With a pKa of around 16–19, they are, in general, slightly weaker acids than water. With strong bases such as sodium hydride or sodium they form salts called alkoxides, with the general formula RO− M+. The acidity of alcohols is strongly affected by solvation. In the gas phase, alcohols are more acidic than in water.

How do you identify alkanes?

The generic formula for alkanes is CnH2n+2, where n is the number identified by the prefix. Alkenes have the formula CnH2n and alkynes use the formula CnH2n-2.

What properties do alkanes have?

PROPERTIES OF ALKANESSaturation. Alkanes are said to be “saturated” and this means that there are the maximum number of hydrogen atoms attached to each carbon. … Polarity. Alkanes are non-polar. … Melting and Boiling Point. … Viscosity.

What is the general formula of alkene?

The general formula for the alkenes is C nH 2n, where n is the number of carbon atoms in the molecule. Decene is an alkene.
