alkane alkene alkyne table

Here’s a handy alkane vs alkene vs alkyne comparison table (for acyclic/open-chain hydrocarbons):

Feature	Alkane	Alkene	Alkyne
Type	Saturated hydrocarbon	Unsaturated hydrocarbon	Unsaturated hydrocarbon
Carbon–carbon bonds	Single (C–C) only	At least one double (C=C)	At least one triple (C≡C)
General formula (one bond)	CₙH₂ₙ₊₂	CₙH₂ₙ	CₙH₂ₙ₋₂
Naming suffix	-ane	-ene	-yne
Hybridization at key bond	sp³	sp²	sp
Geometry (at key carbon)	Tetrahedral (~109.5°)	Trigonal planar (~120°)	Linear (180°)
Example	Ethane: C₂H₆	Ethene: C₂H₄	Ethyne: C₂H₂
Typical reactions	Combustion, substitution (e.g., halogenation)	Addition (H₂, HX, X₂), polymerization	Addition, acidity of terminal alkynes (forms acetylides)
Test (common lab)	No quick decolorization	Decolorizes bromine water / KMnO₄	Also decolorizes bromine water / KMnO₄

Quick tip: the “general formula” row assumes one double (alkene) or one triple (alkyne) bond and no rings. Rings or multiple double/triple bonds change the H count.

If you want, I can also make a first 10 members table (methane → decane, etc.) for each series.

Types of carbon compounds (and how they differ)

Carbon compounds are usually grouped into organic and inorganic carbon compounds.

Key differences (quick and clear)

1) Organic vs inorganic carbon compounds

• Organic: usually contain C–H bonds; huge variety; often lower melting/boiling points (many are liquids/gases); many are covalent and may burn in oxygen.
• Inorganic carbon compounds: often don’t have C–H bonds (e.g., CO₂, carbonates); many are ionic salts with higher melting points (like CaCO₃).

Hydrocarbons: alkane vs alkene vs alkyne vs aromatic (mini-diagram)

text
Alkane:   H3C—CH3        (single bond)
Alkene:   H2C=CH2        (double bond)
Alkyne:   HC≡CH          (triple bond)
Aromatic:  ⌬             (benzene-type ring, very stable)

How they differ

• Alkanes: saturated, single bonds only, less reactive (often substitution reactions).
• Alkenes/alkynes: unsaturated, have π bonds, more reactive (often addition reactions).
• Aromatics: ring systems with special stability (“aromaticity”); react differently than alkenes.

Functional-group compounds (why they’re different)

A functional group is the “reactive part” that controls properties and reactions.

Type	Functional group	One example	What’s different about it
Alcohol	R–OH	ethanol	more polar; can H-bond; higher b.p. than similar hydrocarbons
Ether	R–O–R’	diethyl ether	less polar than alcohols; often solvents
Aldehyde	R–CHO	ethanal	carbonyl at end; easily oxidized
Ketone	R–CO–R’	propanone (acetone)	carbonyl in middle; not easily oxidized like aldehydes
Carboxylic acid	R–COOH	ethanoic acid	acidic; strong H-bonding; often high b.p.
Ester	R–COO–R’	ethyl ethanoate	often sweet smells; formed from acid + alcohol
Amine	R–NH₂ etc.	ethylamine	basic; can form salts with acids
Haloalkane	R–X	chloroethane	reacts in substitution/elimination; useful in synthesis

If you tell me your grade level (middle school / high school / college), I can simplify or deepen the diagram and add 2–3 example structures for each type.
