Carbon Skeleton – Chemistry Practice Exam
The key terms of Chemistry Practice Exam include, Carbon Skeleton, R-OH, functional groups, ammonium molybdate, oxidizing agent, Nitric Acid, acidifying agent, ethyl alcohol, Sublimation, Cyanide poisoning.
The compound R-OH represents
an alcohol
functional groups
Collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties
ammonium molybdate
oxidizing agent used to oxidize phosphorous to phosphate
activated charcoal
substance used as decolorizing agent
Seeding
Scratching the side of the vessel
Stirring
Agitation
Indirect nucleus formation can be done using
Table salt out
Odd one out
odd one out
Alcohol = rubefacient
Calcium carbonate = antiseptic
Sucrose = viscosity builder
Urea = fertilizer
Which among the following elements can form a bond with carbon?
Nitrogen
Carbon
Hydrogen
Halogens
Oxygen
Nitric Acid
used as acidifying agent for sodium fusion extract
conductivity test
It refers to the degree of ionization of compounds:
true about ethyl alcohol
known as grain alcohol
Can be used as antiseptic and disinfectant
Sublimation
refers to the direct conversion of a substance from a solid to gas without passing through the liquid state.
Violet color
Sodium thionitroprusside color is
Kjeldahl method
used to quantitatively determine the amount of nitrogen in the given sample
yellow
Presence of phosphorous produces precipitate.
