You might be single right now but that does not mean that it is the end of the world. You have not just meet the right person for you at this moment. But trust me you will and you will be happy. Also death is never the answer you have so much to still do. You can accomplish so much in your life if you just believe in yourself. For your answer if you are beautiful you are everyone is beautiful in there own way. If anyone called you ugly or if call yourself ugly. Why do you look in the mirror and tell yourself that you are beautiful. You should not care what other people think about. If your happy and love yourself then why care what others think. Because in the end the only opinion that matters is your own.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
