 Among the following the compound that do not containing P-P overlapping is ?

a) H2
b) BeCl2
c) F2
d) HF

Solution :- 

For p-p overlap both atoms must have unpaired electrons in p-orbitals.

H- $1s^1$

Be- $1s^2$$2s^2$

Cl- $1s^2$$2s^2$$2p^6$$3s^2$$3p^5$

F- $1s^2$$2s^2$$2p^5$

If you see here , only F and Cl have unpaired electron in vacant shell. 
But Cl is forming bond with Be which has s-orbital.
while F has 'p' orbital and it is shairing electron with other p-orbital of F.

Hence D is the correct answer . i.e. HF compound .

What is Github and How we can use it with basic commands ? #Linux #Github #Devops

 

What is Github and How we can use it 

1. GitHub is one of the world’s largest community of developers.

2. GitHub has a number of useful features that enable development teams to         work together on the same project 

3. Easily create new versions of software without disrupting the current                    versions.

Benefit

 This allows you to work on code with anyone from anywhere. Additionally,         many employers use GitHub.

#git branch  // it will give current working branch name .

#git checkout branch_name //it will switch the existing branch name .

#git checkout -b branch_name // it will create new branch which will be parallel to parent branch .

#make you required changes in particular file for e.g. xyz.c .

git add xyz.c

git commit -m "commit_msg"

 git push origin branch_name // it will push your changes into github so that you can raise pull request .
