In most cases their functions are the same.The only diffrence is that when you use "whether",you can use the pattern of "whether ...or not".However,when you use "if",you cannot use that pattern.
For examples:
I don't know whether she will come.
or:
I don't know whether she will come or not.
I don't know if she will come.
But,you cannot say:
I don't know if she will come or not.
Besides,sometimes it is not bad to use a different word when too many "if's" are in a sentence.
For an example:
If you are not sure about her decission,why don't you ask her whether she will come to your birthday party or not?
Compare that with the following sentence:
If you are not sure about her decission,why don't you ask her if she will come to your birthday party?

是的 但句中若有or not时，不能用whether

我想你是在问"宾语从句"吧.或者叫"直接引语"变"间接引语". (高一语法重点)
关于引导词:
1. 从句是陈述句
THAT来引导
eg. "I will be back soon."he said.
He said (that) he would be back soon.
2. 从句是一般疑问句
IF,WHETHER都...

我想你是在问"宾语从句"吧.或者叫"直接引语"变"间接引语". (高一语法重点)
关于引导词:
1. 从句是陈述句
THAT来引导
eg. "I will be back soon."he said.
He said (that) he would be back soon.
2. 从句是一般疑问句
IF,WHETHER都可以
eg. "Will he be back soon?"she asked.
She asked if/whether he would be back soon.
3. 从句是特殊疑问句
疑问词来引导
eg. "When will he be back?" a girl asked.
A girl asked when he would be back.
除此以外还应注意"时态""人称""表示时间地点"等词的变化.
建议去语法网站查阅有关"宾语从句"的章节.

从句若表“是否”时,if,whether 均可以.特殊问句做宾语,仍用原来疑问词.帮忙举例说明下,谢．追分 whether/if（表是否时）引导的从句可以是相对的吗 e.g.whether they would pass the exam or not. 合并宾语从句时,若从句为一般疑问句,什么时候用if,什么时候用whether? 合并宾语从句时,若从句为一般疑问句,什么时候用if,什么时候用whether?jutide if和whether后引导宾语从句时为是否,但为什么还可在后面加or not,也翻译成是否,有区别吗 if和whether引导表示“是否”的一般疑问句的宾语从句. whether/if引导的宾语从句 宾语从句什么时候用if,whether,that whether表是否后+宾语从句 宾语从句可以换成一般疑问句求例句 宾语从句,whether和if的用法如：他问我这本书是否值得读.翻为：He asked me whether?if?the book was worth reading .此句中用whether还是if?我觉得两者都可,规则1、有 or not 时只能用whether2、在介词后只能用w 动词后的宾语从句表示“是否”的意思的都用whether而不能用if if如果是否 主句从句if当如果,是否时主句从句应该各为什么时态 一般疑问句作宾语从句时if可否全部替换为whether?一般疑问句作宾语从句时用连接词if或whether,那么if可否全部替换为whether? 作哪些动词的宾语从句时用whether 不用if 请介绍一下whether,if的区别.在引导从句时. 宾语从句中if和whetherif,wheter在宾语从句中的区别①if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if whether与or not在句中不相邻时whether是否可以改为ifIt is a question whether he will come or notwhether 是否可换成if 英语复合句中的宾语从句的引导词whether是否可以完全替代if?我们知道很多情况不能用if而不能用whether,那么什么情况只能用if吗?
