I need all the molecular formula of alkane, alkene, alkyne, benzene, alcohol, alkanoic acid, aldehydes, ketone, and others

Here are the general molecular formulas for the requested classes of organic compounds:

• Alkane: $\text{C}_n\text{H}_{2n+2}$ (where $n \ge 1$)
• Alkene: $\text{C}_n\text{H}_{2n}$ (where $n \ge 2$, for compounds with one carbon-carbon double bond)
• Alkyne: $\text{C}_n\text{H}_{2n-2}$ (where $n \ge 2$, for compounds with one carbon-carbon triple bond)
• Benzene: $\text{C}_6\text{H}_6$ (This is a specific aromatic compound)
• Alcohol: $\text{C}_n\text{H}_{2n+2}\text{O}$ (where $n \ge 1$)
• Alkanoic acid (Carboxylic acid): $\text{C}_n\text{H}_{2n}\text{O}_2$ (where $n \ge 1$)
• Aldehyde: $\text{C}_n\text{H}_{2n}\text{O}$ (where $n \ge 1$)
• Ketone: $\text{C}_n\text{H}_{2n}\text{O}$ (where $n \ge 3$)
