What does Ketal mean?

What does Ketal mean?

In organic chemistry, a ketal is a functional group derived from a ketone by replacement of the carbonyl (C=O) group by two alkoxy groups. The IUPAC once declared the term “ketal” obsolete, but later accepted it as a subclass of acetals. Therefore, a ketal can also be defined as “an acetal derived from a ketone.”

What is Ketol?

[ kē′tôl′, -tōl′ ] n. A compound having an alcohol and ketone group.

What is the meaning of imines?

An imine (/ɪˈmiːn/ or /ˈɪmɪn/) is a functional group or chemical compound containing a carbon–nitrogen double bond. The nitrogen atom can be attached to a hydrogen (H) or an organic group (R). The carbon atom has two additional single bonds. The term “imine” was coined in 1883 by the German chemist Albert Ladenburg.

What does Hierolatry mean?

worship of saints
Definition of hierolatry : worship of saints or sacred things.

What is Ketal how it is formed?

Ketals and acetals are formed by reaction of the carbonyl with alcohols such as methanol or ethanol under anhydrous conditions, in the presence of an acid catalyst. It is obvious that many alcohols can be used to generate acetals and ketals, but methanol and ethanol are probably the most common ones used.

What is Cyclic Ketal?

A cyclic ketal is a ketal in the molecule of which the ketal carbon and one or both oxygen atoms thereon are members of a ring. eg: see also cyclic acetal.

What is the structure of Ketal?

An acetal is an organic molecule where two separate oxygen atoms are single bonded to a central carbon atom. Acetals have the general structure of R2C(OR’)2.

What is ketal example?

Ketal:- When a ketone reacts with ethylene glycol in the presence of dry HCl gas, a cyclic product in formed which is called a ketal.

What is ketal reaction?

Ketal is a functional group which is derived from ketone by replacing the carbonyl group with two alkoxy groups. Ketal is prepared by the reaction of ketone with alcohols like methyl alcohol or ethyl alcohol under anhydrous condition. Ketone reacts with alcohol in presence of acid catalyst.
