Organic Reactions. Two fundamentally different reducing agents have been used to add hydrogen across a double bond. A metal can be used to catalyze the reaction between hydrogen gas and the C=C double bond in an alkene. A source of the hydride (H -) ion, on the other hand, is used to reduce C=O double bonds.the Double C menu High quality at a fair price.

Carbon–carbon double bonds (C═C) are ubiquitous in natural and synthetic polymers. In bulk studies, due to limited ways to control applied force, they are thought to be mechanically inert and not to contribute to the extensibility of polymers. Here, we report a single molecule force spectroscopy study on a polymer containing C═C bonds using …

a) Allyl bromide. b) Vinyl bromide. c) Tert-Butyl bromide. d) Propylidene bromide. Answer: a. Explanation: The parent chain of 3-Bromopropene has three C atoms, with a double bond at C-1 and Br at C-3. As a result, it is an allylic halide because Br is connected to the C adjacent to the C-C double bond. 5. The C99 standard includes new real floating-point types float_t and double_t, defined in <math.h>.

Rvalue references are one of the more important new things in the upcoming standard; they enable support for 'move' semantics on objects and permit perfect forwarding of function calls.

A double type variable is a 64-bit floating data type. The double is a fundamental data type built into the compiler and used to define numeric variables holding numbers with decimal points. C, C++, C# and many other programming languages recognize the double as a type. A double type can represent fractional as well as whole …double and float. The doubles and floats are datatypes used to declare decimal type variables. They are similar, but doubles have 15 decimal digits, and floats only have 7.
