A compound of hydrogen with another, more electropositive element. Typically, the elements in Group 1 or Group 2 of the Periodic Table will form hydrides when combined with H (for instance, CaH2). Usually H forms a positive ion, H+, but when combining with certain very electropositive elements (in other words, elements that are NOT very electronegative), it forms a negative ion, H-, because H is more electronegative than many of the Group 1 and Group 2 metals. Since H isn't very electronegative compared to most elements, it is much more often H+ than H-.

Is phthalic anhydride polar?
anhydride is polar acceptor
Which reagent is limiting cyclopentadiene or maleic anhydride?
Maleic Anhydride.
What is the anhydride of Triflic acid?
Trifluoromethanesulfonic anhydride = (CF3SO2)2O
What is RaCO3 Is it an acid base salt acid anhydride or basic anhydride?
RaCO3 is a salt
What is the anhydride of nitric acid?
Nitric acid does not form the anhydride but dinitrogen penta oxide is theoretical anhydride of nitric acid.2HNO3 = N2O5 + H2O==========No. From the Wikipedia article on nitrogen pentoxide:N2O5 was first reported by Deville in 1840, who prepared it by treating AgNO3 with Cl2.Therefore, nitrogen pentoxide is the anhydride of nitric acid.

Is acetic anhydride an acid or a base?
An anhydride is not an acid and not a base.
What is an anhydride?
An anhydride is a compound formally derived from another by the loss of a water molecule.
What is the use of maleic anhydride in alkyd resin?
It use to reduce the part of phthalic anhydride
What is RaCO3 Is it an acid base salt acid anhydride or basic anhydride?
RaCO3 is a salt

What is the product of anthrance with maleic anhydride?
The product of the reaction between anthracene and maleic anhydride is known as anthracene-maleic anhydride adduct. This adduct is commonly used in the synthesis of dyes, polymers, and other organic compounds.
Is phthalic anhydride is soluble in methanol?
Phthalic anhydride is slightly soluble in methanol. But beware! In this case, phthalic anhydride will actually react with its solvent. This is called estrification of the anhydride. Methanol will break the ring of Phthalic anhydride and make an ester. C6H4(CO)2O + CH3OH --> C6H4(CO2H)(CO2CH3) Similarly, you might THINK Phthalic anhydride is soluble in water, but it actually reacts with water to make phthalic acid. If you want to make a true solution of phthalic anhydride, I would recommend acetone, or methylethyl ketone.
What would happen if the excess acetic anhydride is not removed in the reaction vessel?
If the excess acetic anhydride is not removed in the reaction vessel an unwanted reaction will occur. The acetic anhydride will react causing esterification.
Which oxide of nitrogen is also called as mixed anhydride?
Nitrogen Dioxide-NO2 is also called as mixed anhydride.
