Classify the compound below as an alkane, alkene, alkyne, alcohol, aldehyde, amine, and so forth
Gnoma [55]

<em>Answer:</em>

  • Organic compounds are those which are derivatives of hydrocarbons. They are classified into following functional groups.

<em>Alkane:  </em>

  • Alkane are simplest hydrocarbons.
  • They have general formula CnH2n+2. These hydrocarbons contain single bond.
  • For example ethane , H3C----CH3.

<em>Alkene:</em>

  • Alkene are most reactive.
  • They have general formula CnH2n.
  • These contain double bond in their structure.
  • For example , ethene, H2C=CH2

<em>Alkyne:</em>

  • These are less less reactive as compare to alkenes.
  • They have general formula CnH2n-2.
  • They contain triple bonds in their structure.
  • For example Acetylene HC≡CH

<em>Alcohol:</em>

Alcohol have functional group OH. They have general formual R---OH, R may be alkyl group.For example Ethanol H3CH2C---OH

<em>Amine:</em>

  • Amine contain NH2 F.G.
  • They have general formula R---NH2.
  • There are three types of amine like primary, secondary and tertiary amine.
  • For example H3CH2C---NH2

<em>Aldehyde:</em>

  • Aldehydes have CHO F.G .
  • They have general formula R--CHO.
  • For example H3CH2C---CHO

<em>Ketone:</em>

  • Ketones have R--CO--R functional group.
  • For example acetone H3C---CO---CH3

<em>Carboxylic acid:</em>

  • They functional group COOH.
  • Their general formula is R---COOH.
  • For example Acetic acid H3C---COOH

4 moles of hydrogen react with 5 moles of oxygen to form water, identify the excess reagent?
Fynjy0 [20]

Answer:

Excess Reagent = oxygen

Explanation:

Limiting reagent: The substance that is totally consumed when the reaction is completed.

Excess reagent: The substance left after the limiting reagent is consumed completely

The balanced chemical equation for formation of water is as follow:

2H_{2}+O_{2}\rightarrow 2H_{2}O

This means when 2 moles of hydrogen reacts with 1 mole of oxygen, 2 moles of water is produced.

Hence the ratio in which hydrogen and oxygen gas reacts is 2:1

Now if 2 mole hydrogen require 1 mole of oxygen ,then 4 mole hydrogen need 2 mole of oxygen.

H_{2}:O_{2}=2:1

or

H_{2}:O_{2}=4:2

Here 5 mole of oxygen is reacting but only 2 mole is required .

Oxygen is in excess.
