Are exothermic reactions decomposition reactions or are they synthesis reactions?
Synthesis reactions are generally characterized by being exothermic. Decomposition reactions are usually endothermic.
What are all reactions in the body called?
Generally in a body two type of reactions take place, catabolic and anabolic. Catabolic reactions are the type of reactions in which bio-molecules in our body split into their constituents to release energy; while anabolic reactions are those reactions in which new bio-molecules are synthesized in our Body. Together both reactions are known as METABOLISM.
How do carbon dioxide molecules enter the light dependent reactions?
false its light independent reactions
When an acid and an alkali react it is called combustion?
No. Acid + alkali reactions are neutralisation reactions. Combustion is a reaction with oxygen.
Why are combustion reactions considered exceptions to the rules of chemical reactions?
Combustion Reactions are always reacted with Oxygen gas in this case if you had C3H8+O2 you will ALWAYS get H2O+CO2 it does not matter if you have C100H54+O2 you will still get H2O+CO2 this is why combustion reactions are considered exceptions to the rules of a product or chemical reaction.
What are the chemical tests to distinguish between cyclohexanol and phenol and what reactions are involved?
the difference between cyclohexane and cyclohexene is the difference between an alkane and an alkene. Add bromine water to both samples. cyclohexane will remain orange. cyclohexene will turn the orange solution colourless because bromine adds across the double bonds. Propanol gives effervescence of hydrogen with sodium metal, propanone does not. Propanone and 2-propanol answer iodoform test, 1-propanol does not Benzoic acid and propanoic acid gives effervescence of carbon dioxide with sodium bicarbonate, benzaldehyde and propanoic chloride does not.
Why iodobenzene cannot be prepared by Gattermann reaction?
The Gatterman reaction is used to convert benzene to benzaldehyde (and derivatives). You need to use the Sandmeyer reaction to add iodo groups to aromatic rings. I think textbooks sometimes gets the two reactions mixed up.
Effect of conjugation in the frequency of absorption of carbonyl group for cinnamaldehyde and benzaldehyde as compared to n-butyraldehyde?
Aldehydes are highly reactive and participate in many reactions.[8]" From the industrial perspective, important reactions are condensations, e.g. to prepare plasticizers and polyols, and reduction to produce alcohols, especially "oxo-alcohols." From the biological perspective, the key reactions involve addition of nucleophiles to the formyl carbon in the formation of imines (oxidative deamination) and hemiacetals (structures of aldose sugars).[8]
How will you prepare hexyne from ethyne?
1. Explain with suitable examples: a) Both chlorobenzene and chloroethene do not undergo substitution reactions under ordinary conditions with NaOH. b) Carbonyl group of benzaldehyde is less reactive towards nucleophilic addition reactions than the carbonyl group of ethanal. 2. Write the product (s) and mechanism for the following reactions: (5) 3. How would you carry out following conversions? a) Ethene to oxirane b) Benzyl magnesium chloride to 3-phenylpropanol c) Propene to glycerol d) Benzaldehyde to 3-phenylpropenoic acid e) Ethanol to trichloromethane (5) 4. a) How would you differentiate between different classes of alcohols? b) Give two reduction methods which can convert a carbonyl compound to an alkane.
What is the use of acetylides formation?
Acetylide formations are very useful inorganic chemistry reactions in combining carbon chains, particularly addition and substitution reactions.
Distinguish between the light and dark reactions of photosynthesis?
Chlorophyll in dark habitats contain less enymes than in lighter areas so the reaction time of photosynthesis is increased by the rate of chloroplasts per ribasone.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
The two major sets of reactions involved in photosynthesis are?
Light Reactions and the Calvin Cycle Reactions.
Are exothermic reactions decomposition reactions or are they synthesis reactions?
Synthesis reactions are generally characterized by being exothermic. Decomposition reactions are usually endothermic.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What kinds of reactions are redox reactions?
Electron transfer reactions. reactions involving losing and gaining electrons
