Answer:

Explanation:1. NaNH2 (1-Butene)

CH3CH2CH2CH2Cl --------------> CH3CH2CH=CH2 + HCl (elimination reaction)

2. Br2, CCl4

CH3CH2CH=CH2 ---------------> CH3CH2CH(Br)CH2Br (Simple addition Reaction)

3. NaNH2 (1-Butyne)

CH3CH2CH(Br)CH2Br ----------------> CH3CH2C≡CH + 2HBr

Sodamide (NaNH2) is a very strong base and generally results in Terminal Alkynes when treated with Vicinal Dihalides.

Alcoholic KOH on the other hand results in the formation of Alkynes with triple bonds in the middle of the molecule.

nignag [31]

Answer:    

The prefix di means 2 and the prefix hexa means 6.

As per IUPAC rules you must use the prefixes to indicate the number of atoms of each element in the formula.

So, the proper name for the compound C2H6 is dicarbon hexahydride.

Determine the element of lowest atomic number that contains a complete d subshell in the ground state. element symbol:
allsm [11]

The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .  

Further Explanation:  

atomic number:  

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.  

The elemenents of the intermittent table arranged by atomic mass:  

atomic Mass    Name substance element          Number  

1.0079                          Hydrogen                            1  

4.0026                            Helium                                    2  

6.941                           Lithium                                    3  

9.0122                           Beryllium                                    4  

atomic number speak to:  

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.  

Meaning of subshell:  

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.
